Much has been written about how much national polling was off in the 2020 election. A recent article from FiveThirtyEight asks Why Was The National Polling Environment So Off In 2020?. The article begins:

Heading into the 2020 election, Democrats were favored to not only capture the presidency but also win back the Senate and retain their sizable majority in the House. Much of that came down to the overall national environment, which appeared to be pretty favorable to Democrats, as they held a 7.3-point lead in FiveThirtyEight's final polling average of congressional polls.

A New York Times article from November 12, 2020 is titled 'A Black Eye': Why Political Polling Missed the Mark. Again. It begins by listing some of the bad predictions:

Senator Susan Collins did not lead in a single publicly released poll during the final four months of her re-election campaign in Maine. But Ms. Collins, a Republican, won the election comfortably.

Senator Thom Tillis, a North Carolina Republican, trailed in almost every poll conducted in his race. He won, too.

And most polls underestimated President Trump's strength, in Iowa, Florida, Michigan, Texas, Wisconsin and elsewhere. Instead of winning a landslide, as the polls suggested, Joseph R. Biden Jr. beat Mr. Trump by less than two percentage points in the states that decided the election.

It is possible to check these numbers in the Shiny application at https://econdata.shinyapps.io/voting_538/. Going to that URL will display the following page:

The first column contains the two-letter state abbreviation for each state plus DC (District of Columbia). This can be changed to the full name by checking the "Show full state" checkbox at the bottom of the leftmost panel. The next two columns give the percentage of the total vote for the primary Democratic and Republican candidates in the first race (specified by the first race selected under the "Races, x & y axes" label). The next column, MARGIN1, is the Democratic percentage minus the Republican percentage and the next column, TOTAL1, is the sum of the two percentages.

The next four columns are the same items as the last four except that they are for the second race (specified by the second race selected under the "Races, x & y axes" label). The next four columns are the "shifts" between the two prior groups of four columns and is obtained by subtracting each of the first four columns from the corresponding column in the second four columns. Hence, the first value of -1.39 for MAR_SH (short for "Margin Shift") is equal to the first MARGIN2 value of -10.06 minus the first MARGIN1 value of -8.68 (with roundoff error).

Finally, FLIP indicates any states for which the margin shift caused a prediction for a win by one party to be followed by an actual win by the other party. As can be seen, this happened in Florida and North Carolina in the 2020 presidential election. Florida was predicted to favor Democrats by 2.48 percent but ended up favoring Republicans by 3.36 percent, a swing of 5.84 percent. Likewise, North Carolina was predicted to favor Democrats by 1.78 percent but ended up favoring Republicans by 1.35 percent, a swing of about 3.12 percent.

Changing the "Units" select list on the far left panel from "Percent" to "Count" will cause the following actual vote counts to display:

Getting a Plot of the Shift via the Plot Tab

Changing the Units select list back to "Percent" and clicking on the Plot tab will display the following page:

Shift in Margin Vote Share from President_538_deluxe_2020 to President_2020 Race in U.S. (Plot Percent)

In the above plot, the x-coordinate of each point is equal to its margin in the first race. The y-coordinate is equal to its margin in the second race MINUS its margin in the first race. Hence, the y-coordinate is the SHIFT in the margin from the first to the second race. On both axes, the positive direction is defined to be more Democratic. Hence, the plot shows that only the margins of three states, Colorado, Louisiana, and Maryland, became more Democratic in the final results. All of the rest became more Republican. This shift to the right has been called the "red shift" as described here.

The dashed line has special significance. It is the line representing y = -x. As stated above, x is equal to Margin1 and y is equal to (Margin2 - Margin1). Taking M to be Margin, the dashed line represents (M2 - M1) = -M1. Adding M1 to both sides gives M2 = 0. Hence, the dashed line basically represents the y-axis of the second race. This means that the points between the solid y-axis and the dashed y-axis are points that, being left of one axis and right of the other, switched sides or "flipped" because of the shift. As expected, these include Florida (FL) and North Carolina (NC). Georgia (GA), Arizona (AZ), and Wisconsin (WI) can be seen to have almost flipped due to the shift and Iowa (IA), Ohio (OH), and Texas (TX) can be seen to have been predicted to be close but were not due to the red shift.

One other item of note for this plot is that the "Position above" and "Position below" fields have been set to "VA,MN" and "DE", respectively. This simply causes those labels to begin above or below the actual points so as to avoid overlapping with other labels. These two-letter state abbreviations must be used regardless of whether or not the full state names are being displayed. All of the settings in this second-from-the-left panel can be saved by clicking on the Save button at the bottom of that panel. The settings will be saved as the next free version number so that no settings are overwritten. Hence, the only way currently to edit or delete prior settings are to edit the files.

As can be seen, all of the visible states are some shade of red and only Colorado, Louisiana, and Maryland are a shade of blue. Alaska and Hawaii are not visible on this map but they can be seen to be red by pressing down on a mouse button and dragging the map in the proper direction. Also, the color of Washington D.C. is not discernible but panning over to its location and hitting the + key in the upper left of the map to zoom in reveals that it is likewise red. It's always possible to get back to the original map by changing the "Map Variable" to another variable and then setting it back to MAR_SH.

Changing the "Map Variable" to FLIP causes all of the states to become gray except for North Carolina and Florida. This is because both of these two states were flipped by the red shift from a predicted win for Democrats to an actual win for Republicans. Changing the field "Close %" on the leftmost panel from 0 to 0,3 causes the states Nevada, Arizona, Georgia, Pennsylvania, Michigan, and Wisconsin to also be colored red. This is because the actual vote margins for these 6 states were all within 3 percent. They were all losses for Trump so it was likely no coincidence that the six states that Trump lost by less than 3 percent were the six states that he contested. North Carolina also had a margin of less than 3 percent but it was in Trump's favor. Florida had a margin of 3.36%in Trump's favor. Finally, changing the field "Close %" to 3,3 (or just 3) causes Iowa, Ohio, and Texas to also be colored red. This is because these 3 states were predicted to have a margin of less than 3 percent. The red shift in all 3 caused their final margins to be greater than 3 percent in Trump's favor. Following is the screen at this point:

Shift in Margin Vote Share from President_538_deluxe_2020 to President_2020 Race in U.S. (Flip or within 3 Percent)

As can be seen, all 11 non-gray states are some shade of red, indicating that there were red shifts from their predicted results to their actual results. North Carolina and Florida were predicted to favor Biden but ended up in Trump's favor. Nevada, Arizona, Georgia, Pennsylvania, Michigan, and Wisconsin were predicted to be in Biden's favor by less than 3 percent and were won by Biden despite red shifts. Those 6 states were all contested by Trump. Finally, Iowa, Ohio, and Texas were all predicted to favor Trump by less than 3 percent but ended up favoring him by more due to the red shift.

Comparing the Actual Election Results of Two Races

It's possible to compare the actual results from any two races that share the same areas (states or districts). Setting the "Races, x & y axes both to President, setting "Year, x-axis" to 2016 and "Year, y-axis" to 2020 compares the presidential races of 2016 and 2020. Clicking on the Plot tab will display the following page:

Shift in Margin Vote Share from President_2016 to President_2020 Race in U.S. (Plot Percent)

As can be seen, Arizona, Georgia, Michigan, Pennsylvania, and Wisconsin are between the solid and dashed y-axes and are the 5 states that were lost by Clinton in 2016 but won by Biden in 2020. Also noteworthy is that all but 8 states are above the x axis, indicating that their vote became more Democratic in 2020. Those 8 states are Arkansas (AR), California (CA), Florida (FL), Hawaii (HI), Illinois (IL), Nevada (NV), New York (NY), and Utah (UT). This suggests that most of the states, for whatever reason, moved away from Trump. It does not seem to support the idea that their was some unique fraud going on in the 6 states that Trump contested.

Clicking on the Map tab will display the following page:

Shift in Margin Vote Share from President_538_deluxe_2020 to President_2020 Race in U.S. (Map Percent)

This again shows that all but the 8 states mentioned above experienced a "blue shift" from 2016 to 2020. That is, their vote shifted toward the Democrats between the 2016 and 2020 Presidential races.

Getting the Races and Years Available via the Data Tab

This application is under continuing development. To see what races and years it currently has data for, select the Data tab. Currently, it will display the following tables:

               Race 2020 2016 2012

8    Map__House_538_deluxe    5    0    0
As can be seen, the app currently has data for the 2020, 2016, and 2012 Presidential race. It also has data for the predictions from
FiveThirtyEight for the 2020 Presidential Election. For the Senate, it currently has the final results of the 2020 Senate races and of the _deluxe model for the 2020 Senate races from FiveThirtyEight. The Senate and House predictions from FiveThirtyEight have a _lite, _classic, and _deluxe model. For the House, the app currently has the final results of the 2020 House races and of the _deluxe model for the 2020 House races from FiveThirtyEight. The table shows the number of data records in each data set. As can be seen, the numbers are the same between the predictions and actual results for the Senate and House but differ for the President. That's because the FiveThirtyEight data includes vote counts for ME-1 and ME-2 in Maine and for NE-1, NE-2, and NE-3. The data for the final results does not contain these areas so they are ignored when comparing the predictions and that race.

The second table just contains the saved parameters that exist. Each file of parameters correspond to a specific race (the first race) and year and can include more than one full set of parameters. The parameter totals of 12, 24, and 36 for the Plot parameters correspond to 1, 2, and 3 full sets of saved parameters. The parameter totals of 5 and 10 for Map parameters correspond to 1 and 2 full sets of saved parameters.

Comparing the Senate Predictions and Results via the Output Tab

Change the two races following the "Races, x & y axes" to Senate_538 and Senate and make sure that "538 Model", "Year, x-axis", and "Year, y-axis" are set to _deluxe, 2020, and 2020, respectively. If you then click the Output tab, you will get the following table:

The prior tables show Georgia (GA), Maine (ME), and North Carolina (NC) are shown to have "flipped". Being positive, the Georgia number indicates a flip from a prediction of a Republican win to an actual Democrat win. The negative numbers for Maine and North Carolina indicates a flip from a prediction of a Democrat win to an actual Republican win. Wyoming is marked as a flip due to a mislabeling of parties in the input file from the MIT data site. I should be able to fix it in a day or two.

Comparing the Senate Predictions and Results via the Plot Tab

Clicking on the Plot tab will display the following plot:

Shift in Margin Vote Share from Senate_538_deluxe_2020 to Senate_2020 Race in U.S. (Plot Percent)

As can be seen, Georgia (GA) is between the solid and dashed y-axes above the x-axis, indicating a flip from a prediction of a Republican win to an actual Democrat win. Maine (ME) and North Carolina (NC) are between the y-axes below the x-axis , indicating a flip from a prediction of a Democrat win to an actual Republican win. Also noteworthy is that all of the states except Colorado (CO) and Georgia (GA) are below the x-axis. This indicates that all of those states had red shifts whereby the actual results were more Republican than the predictions.

Comparing the Senate Predictions and Results via the Map Tab

Clicking on the Map tab will display the following plot:

Shift in Margin Vote Share from Senate_538_deluxe_2020 to Senate_2020 Race in U.S. (Plot Percent)

The gray states are those in which there was no Senate race in 2020. As can be seen, all of the states with Senate races had a red shift except for Colorado and Georgia. West Virginia and Rhode Island had especially strong red shifts -18.27 and -14.91 percent, respectively.

Changing the "Map Variable" to FLIP causes all of the states to become gray except for Georgia, Maine, and North Carolina. This is because Georgia was flipped by a blue shift and Maine and North Carolins were both flipped by the red shift from a predicted win for Democrats to an actual win for Republicans. Changing the field "Close %" on the leftmost panel from 0 to 0,3 causes Arizona and Michigan to also be colored red. This is because the actual vote margins for these 2 states were all within 3 percent. Finally, changing the field "Close %" to 3,3 (or just 3) causes Iowa to also be colored red. This is because it was predicted to have a margin of less than 3 percent. The red shift caused its final margins to be greater than 3 percent in the Republican's favor. Following is the screen at this point:

Shift in Margin Vote Share from Senate_538_deluxe_2020 to Senate_2020 Race in U.S. (Plot Percent)

As can be seen, all 6 non-gray states except Georgia are some shade of red, indicating that there were red shifts from their predicted results to their actual results.

Comparing the House Predictions and Results via the Output Tab

Change the two races following the "Races, x & y axes" to House_538 and House and make sure that "538 Model", "Year, x-axis", and "Year, y-axis" are set to _deluxe, 2020, and 2020, respectively. If you then click the Output tab, you will get the following table:

As can be seen, 19 House districts flipped from their predicted to their actual results and all but one of them flipped from a predicted Democrat win to an actual Republican win.

Comparing the House Predictions and Results via the Plot Tab

Clicking on the Plot tab will display the following plot:

Shift in Margin Vote Share from House_538_deluxe_2020 to House_2020 Race in U.S. (Plot Percent)

As can be seen, the plot forms something of a barbell visual with the left end of it being a collection of solid Republican districts vertically centered close to the x-axis. The right end of the barbell is a collection of solid Democrat districts but it is vertically centered well below the x-axis. This suggests that the solid Republican districts are not shifted on average but that the solid Democrat districts are markedly red shifted on average. It's unclear what the cause of this is. One possible explanation is that the solid Democrat districts tend to be urban and those districts may experience more voter suppression. There may be more urban, Democrat voters who intended to vote but were dissuaded from doing so by long lines or other voting problems, purposeful or not. There may also have been more of such voters who thought that they had voted but whose votes were rejected due to non-matching signatures on mail-in ballots or problems with provisional ballots. Of course, some systematic flaw in the polling or some other election irregularities are also possible factors.

In order to take a closer look at those districts which flipped, it's possible to set the ranges of the x and y axes to focus in on them. These changes were in fact saved and can be recalled by changing the number in the "Load" input at the bottom of the second left-most panel to 3. This results in the following plot:

Shift in Margin Vote Share from House_538_deluxe_2020 to House_2020 Race in U.S. (Plot Percent)

As can be seen, the Georgia district GA-7 is between the solid and dashed y-axes above the x-axis, indicating a flip from a prediction of a Republican win to an actual Democrat win. The other 18 flipped districts are all between the y-axes below the x-axis , indicating a flip from a prediction of a Democrat win to an actual Republican win. The three districts with the largest red shifts include two districts near Miami, Florida (one which was held by Donna Shalala, the former Secretary of Health and Human Services under Bill Clinton from 1993 to 2001). The other one of the 3 was the one of the 4 Iowas districts.

Comparing the House Predictions and Results via the Map Tab

Clicking on the Map tab will display the following plot:

Shift in Margin Vote Share from House_538_deluxe_2020 to House_2020 Race in U.S. (Plot Percent)

The gray areas are districts in which there were not both Democrat and Republican candidates. These can be seen in the prior long table as those where either the DEM1 or REP1 columns contain 0.00. As can be seen, all 6 non-gray states except Georgia are some shade of red, indicating that there were red shifts from their predicted results to their actual results. As can be seen, some of the strongest red shifts occurred in south Texas, west Mississippi, the Miami Florida area, Iowas, and other locations. The most noticeable blue shifts occurred in Georgia and Louisiana.

Changing the "Map Variable" to FLIP causes all of the districts to become gray except for the 19 which "flipped". Nearly all of these show red shifts, most notably in south Texas and New Mexico, east Iowa, and the Miami, Florida area. Changing the field "Close %" on the leftmost panel from 0 to 0,3 causes another of Iowa's 4 districts to turn red, along with some other districts. This is because the actual vote margins for these districts were all within 3 percent. Finally, changing the field "Close %" to 3,3 (or just 3) causes other districts to turn red, most noticeably in west Colorado, south Minnesota, and central Virginia. This is because they were predicted to have a margin of less than 3 percent. The red shift caused its final margins to be greater than 3 percent in the Republican's favor. Following is the screen at this point:

To get a better idea of what districts were close, it may be useful to refer to the prior long table since some of the smaller districts may not be easily visible. Once those districts have been identified, you can pan to their location and zoom in on them with the + button in the upper left of the map.

Polling Place Equipment of Additional House Races that were listed as Tossup Districts in the New York Times

The following table shows the main polling place equipment used in the key counties (those with the most votes) in house races that were designated as "Tossup districts" in the New York Times but not mentioned in the prior section. These include chiefly races that were tossup races but leaned Republican and shifted further Republican. These are listed from the most severe red shift (as judged by the 538 predictions) to the one race (TX-10) that had a blue shift.

Maps Showing Counties that Use Selected Polling Place Equipment

As can be seen in the table in the prior section, all of the districts were projected to lean Republican by less than 4 percent except for MN-7 (-6.45) and TX-10 (-11.81). The following map shows all of the districts that flipped or were projected to have a margin within 4 percent.

Finally, there was a recent article in Politico, titled "The election security hole everyone ignores". It discusses electronic pollbooks and states:

Problems with the devices, known as electronic pollbooks, caused long lines during this year's presidential primary in Los Angeles County and contributed to chaos and hours-long waits during Georgia's primary in June. They led to past years’ snafus in places such as Philadelphia, North Carolina, Indiana and South Dakota.

It also contains an interactive version of the following map.

Comparing Exit Polls and Election Results in the 2020 Presidential Election

An article titled Unadjusted Exit Polls for 2020 Presidential and Senate Races Show Inexplicably Political Red-Shift Pattern Similar to Prior US Elections begins as follows:

Unadjusted Exit Poll (UEP) analysis of the 2020 US Presidential and Senate elections shows the same "red-shift" pattern of Republican favoring discrepancies from Unadjusted Exit Polls (UEPs) particularly in battleground states that has prevailed in every general US Presidential election since 2004.

The article contains links to four tables. Columns 5 and 6 of Table 1 are labeled "Biden UEP" and "Trump UEP" and contain the unadjusted exit polls (UEPs) for Biden and Trump. It is possible to see these exit polls, the final vote margins, and the shifts between them in the Shiny application at https://econdata.shinyapps.io/voting_538/. Go to that URL and make the following changes:

  1. Under "Races, x & y axes", select "President_538" and "President".
  2. Set "Year x-axis" to 2020.
  3. Set "Year y-axis" to 2020.
  4. Enusre that the first "538 Model" is set to "_exitpoll".
This will display the following page:

The first 3 columns match columns 1, 5, and 6 in the Table 1 and the last column contains the shift from the exit poll to the final vote margin for Iowa (IA) and North Carolina (NC), the two states that the flipped from being for Biden in the exit polls but being for Trump in the final vote. Iowa flipped from being 0.9% Biden to being 8.2% Trump and North Carolina flipped from being 0.9% Biden to being 1.3% Trump.

Clicking the Plot tab will display the following plot:

In the above plot, the x-coordinate of each point is equal to the state's margin in the exit poll. The y-coordinate is equal to its margin in the actual vote MINUS its margin in the exit poll. Hence, the y-coordinate is the SHIFT in the margin from the exit poll to the actual vote. On both axes, the positive direction is defined to be more Democratic. Hence, the plot shows that of the 22 states exit polled, only California was more Democratic in the final vote than in the exit poll. All of the rest became more Republican. This shift to the right has been called the "red shift" as described here.

As previously stated, the dashed line has special significance. It is the line representing y = -x. In this formula, x is equal to Margin1 and y is equal to (Margin2 - Margin1). Taking M to be Margin, the dashed line represents (M2 - M1) = -M1. Adding M1 to both sides gives M2 = 0. Hence, the dashed line basically represents the y-axis of the second race. This means that the points between the solid y-axis and the dashed y-axis are points that, being left of one axis and right of the other, switched sides or "flipped" because of the shift. In the triangle bordered by these y axes and below the x-axis are the two states that flipped, Iowa and North Carolina. The exit polls of both states were Democratic but they shifted so far right as to be Republican in the final vote. The 6 states closest to the right of the dashed line are those states that went for Biden by the smallest percentages. Those 6 states were Arizona, Georgia, Michigan, Nevada, Pennsylvania, and Wisconsic (AZ, GA, MI, NV, PA, and WI). The plot and table also show that Florida (FL) was only 0.4% Trump in the exit poll but red-shifted to be 3.4% Trump in the final vote.

Clicking the Map tab will display the following map:

As can be seen, the only state that was above the x-axis in the prior plot (California) is shaded blue indicated that it "blue-shifted" to be more Democratic from the exit poll to the final vote. All of the other states that were polled are shaded red, indicating that they "red-shifted" to be more Republican from the exit poll to the final vote. Iowa, Kentucky, Montana, and Wisconsin red-shifted between 8 and 10 percent and and Michigan red-shifted between 6 and 8 percent.

Changing the selection for "Map Variable" from "MAR_SH" to "FLIP" and ensuring that "Show flips" is checked and "Close %" is zero will display the following map:

The map now colors only those states that "flipped" between the exit poll and the final vote. The map shows that only Iowa and North Carolina flipped. This flipping was caused by Iowa red-shifting 9.1 percent and North Carolina red-shifting 2.2 percent.

Changing "Close %" to 2 will display the following map:

As indicated by the title, the "Close %" value of 2 also colors those states for which the exit poll margin or the final vote margin was within 2 percent. As mentioned above, Iowa and North Carolina "flipped". In addition, Arizona, Georgia, Pennsylvania, and Wisconsin red-shifted to within 2 percent of flipping. Specifically, they red-shifted 5.1, 2.6, 1.8 and 9.9 percent, respectively. Most notable was Wisconsin which red-shifted a massive 9.9 percent. Finally, Florida had an exit poll of 0.4 percent Bush but red-shifted 3 percent to a final vote margin of 3.4 percent.

Comparing Exit Polls and Election Results in the 2020 Senate Elections

As previously mentioned, an article titled Unadjusted Exit Polls for 2020 Presidential and Senate Races Show Inexplicably Political Red-Shift Pattern Similar to Prior US Elections begins as follows:

Unadjusted Exit Poll (UEP) analysis of the 2020 US Presidential and Senate elections shows the same "red-shift" pattern of Republican favoring discrepancies from Unadjusted Exit Polls (UEPs) particularly in battleground states that has prevailed in every general US Presidential election since 2004.

The article contains links to four tables. Columns 5 and 6 of Table 3 are labeled "Dem UEP" and "Rep UEP" and contain the unadjusted exit polls (UEPs) for the Democrat and Republican Senate Candidates. These exit polls are also available in a paper posted at ResearchGate. In addition, there are exit polls for these and some additional states posted at TDMS Research. The following table summarizes all of this data:

As can be seen, the table currently excludes the Senate elections in Georgia, both the two special elections and the two runoff elections.

The first 3 columns match columns 1, 5, and 6 in the Table 3 for those states that exist in Table 3. For all other states, the exit polls come from columns 2 and 3 of the Table 1 at TDMS Research. In any event, the last column contains the shift from the exit poll to the final vote margin for Iowa (IA) and Montana (MT), the two states that the flipped from being for the Democrat candidate in the exit polls but being for the Republican candidate in the final vote. Montana flipped from being 1.3% for the Democrat to being 10.0% for the Republican and North Carolina flipped from being 0.8% Democrat to being 1.7% Republican.

Clicking the Plot tab will display the following plot:

In the above plot, the x-coordinate of each point is equal to the state's margin in the exit poll. The y-coordinate is equal to its margin in the actual vote MINUS its margin in the exit poll. Hence, the y-coordinate is the SHIFT in the margin from the exit poll to the actual vote. On both axes, the positive direction is defined to be more Democratic. Hence, the plot shows that of the 15 states exit polled (excluding Georgia), only New Hampshire was more Democratic in the final vote than in the exit poll. All of the rest became more Republican. This shift to the right has been called the "red shift" as described here.

As previously stated, the dashed line has special significance. It is the line representing y = -x. In this formula, x is equal to Margin1 and y is equal to (Margin2 - Margin1). Taking M to be Margin, the dashed line represents (M2 - M1) = -M1. Adding M1 to both sides gives M2 = 0. Hence, the dashed line basically represents the y-axis of the second race. This means that the points between the solid y-axis and the dashed y-axis are points that, being left of one axis and right of the other, switched sides or "flipped" because of the shift. In the triangle bordered by these y axes and below the x-axis are the two states that flipped, Montana and North Carolina. The exit polls of both states were Democratic but they shifted so far right as to be Republican in the final vote. The 2 states closest to the right of the dashed line (Michigan and Arizona) are 2 of the 6 states that went for Biden by the smallest percentages and were contested by Trump. The plot and table also show that Maine (ME) was only 1.6% Republican (Collins) in the exit poll but red-shifted to be 8.5% Republican in the final vote.

Clicking the Map tab will display the following map:

As can be seen, the only state that was above the x-axis in the prior plot (New Hampshire) is shaded blue indicated that it "blue-shifted" to be more Democratic from the exit poll to the final vote. All of the other states that were polled are shaded red, indicating that they "red-shifted" to be more Republican from the exit poll to the final vote. Alabama red-shifted between 12 to 15 percent, Kentucky and Montana red-shifted between 9 and 12 percent Colorado, Maine, and South Carolina red-shifted between 6 and 9 percent.

Changing the selection for "Map Variable" from "MAR_SH" to "FLIP" and ensuring that "Show flips" is checked and "Close %" is zero will display the following map:

The map now colors only those states that "flipped" between the exit poll and the final vote. The map shows that only Montana and North Carolina flipped. This flipping was caused by Montana red-shifting 11.3 percent and North Carolina red-shifting 2.5 percent.

Changing "Close %" to 2 will display the following map:

As indicated by the title, the "Close %" value of 2 also colors those states for which the exit poll margin or the final vote margin was within 2 percent. As mentioned above, Montana and North Carolina "flipped". In addition, Michigan red-shifted to within 2 percent of flipping. Specifically, it red-shifted 1.7 percent. Finally, Maine had an exit poll of under 2 percent (1.6%) percent Republican but red-shifted 6.9 percent to a final vote margin of 8.5 percent Republican.

Comparing Exit Polls and Election Results in the 2016 Presidential Election

In an article titled Will American Elections Ever Again Be Legitimate?, radio talk show host Thom Hartmann wrote the following:

For example, in the 2016 election, the exit polls showed Hillary Clinton carrying Florida by 47.7 percent to Trump's 46.4 percent, although the "actual" counted vote had Trump winning by 49.0 percent to 47.8 percent. Trump gained 2.5 percentage points . . . somehow.

In North Carolina, exit polls showed Clinton winning 48.6 percent to 46.5 percent, but the votes that were counted turned out with Trump's 49.9 to Clinton's 46.1, a red shift of 5.9 percentage points for the GOP.

Pennsylvania's exit polls showed that Clinton won 50.5 percent to Trump's 46.1 percent, but when "eligible" votes were counted, Trump carried the state 48.8 percent to Clinton's 47.6 percent-a red shift of 5.6 percentage points.

In Wisconsin, it was Clinton beating Trump in the exit polls 48.2 percent to 44.3 percent, but the "real" count put Trump over the top at 48.8 percent to 47.6 percent, a red shift of 5.1 percentage points.

The quote comes originally from Thom Hartmann's book titled "The Hidden History of the War on Voting: Who Stole Your Vote-and How to Get It Back". For the numbers, the book references an article titled 2016 Exit Polls vs. Actual Results: Here's What May Have Happened which includes a table of exit polls from TDMS Research. The exit polls from that table are included in the table below.

Sources: 2016 exit polls from Jonathan Simon,
         2016 exit polls from TDM Research
The above table also contains 2016 exit polls from Jonathan Simon and the last three columns show that the polls only differ slightly for Illinois, New Hampshire, New Jersey, New Mexico, and Utah. This is likely due to the fact that the exit polls are the initial polls that appear on CNN.com and continually change after that as they are adjusted to fit the actual vote as it comes in.

It is possible to view the difference between the exit poll margins from Jonathan Simon and the actual final vote margins in the Shiny application at https://econdata.shinyapps.io/voting_538/. Go to that URL and make the following changes:

  1. Under "Races, x & y axes", select "President_538" and "President".
  2. Set "Year x-axis" to 2016.
  3. Set "Year y-axis" to 2016.
  4. For the first "538 Model", select "_exitpoll".
This will display the following page:

The first 3 columns match columns 1, 3, and 4 in the prior table and the last column contains the shift from the exit poll to the final vote margin for the 4 states that the article mentioned (Florida, North Carolina, Pennsylvania, and Wisconsin) and two states which the exit polls gave as even (Michigan) or nearly even (Minnesota). The shifts of -2.5, -5.8, -5.1. and -4.7 for FL, NC, PA, and WI don't exactly match all of those in the article (-2.5, -5.9, -5.6, and -5.1) because the final vote count was not final on November 10, 2016, the update time of the table it references. Still, it's very close.

Clicking the Plot tab will display the following plot:

In the above plot, the x-coordinate of each point is equal to the state's margin in the exit poll. The y-coordinate is equal to its margin in the actual vote MINUS its margin in the exit poll. Hence, the y-coordinate is the SHIFT in the margin from the exit poll to the actual vote. On both axes, the positive direction is defined to be more Democratic. Hence, the plot shows that the margins of only five of the 28 state polled (CA, MN, NY, TX, and WA) were more Democratic in the final vote than in the exit poll. All of the rest became more Republican. This shift to the right has been called the "red shift" as described here.

As previously stated, the dashed line has special significance. It is the line representing y = -x. In this formula, x is equal to Margin1 and y is equal to (Margin2 - Margin1). Taking M to be Margin, the dashed line represents (M2 - M1) = -M1. Adding M1 to both sides gives M2 = 0. Hence, the dashed line basically represents the y-axis of the second race. This means that the points between the solid y-axis and the dashed y-axis are points that, being left of one axis and right of the other, switched sides or "flipped" because of the shift. In the triangle bordered by these y axes and below the x-axis are the 4 states mentioned in the article (FL, NC, PA, and WI). The exit polls of these states were Democratic but they shifted so far right as to be Republican in the final vote. Michigan (MI) is actually on the y-axis. The exit poll for MI was even (zero) but it shifted Republican in the actual vote. On the other hand, the one state in the triangle bordered by the y axes but above the x-axis, Minnesota (MN), had an exit poll that was slightly Republican but it shifted left to become Democratic in the final vote.

Clicking the Map tab will display the following map:

As can be seen, the five states that were above the x-axis in the prior plot (CA, MN, NY, TX, and WA) are shaded blue indicated that they "blue-shifted" to be more Democratic from the exit poll to the final vote. All were small blue-shifts between 0 and 3 percent except for New York (NY) which blue-shifted between 3 and 6 percent. All of the other states that were polled are shaded red, indicating that they "red-shifted" to be more Republican from the exit poll to the final vote. Utah (UT) and Missouri (MO) red-shifted between 9 and 12 percent and Ohio (OH), Maine (ME), and South Carolina (SC) red-shifted between 6 and 9 percent. Those states for which no exit poll exists are colored gray.

Changing the selection for "Map Variable" from "MAR_SH" to "FLIP" and ensuring that "Show flips" is checked and "Close %" is zero will display the following map:

"Map Year" can also be set to 2016 though this only affects loading and saving of parameters. The map now colors only those states that "flipped" between the exit poll and the final vote. The map shows that North Carolina, Pennsylvania, and Wisconsin red-shifted between 4 and 6 percent, Florida red-shifted between 2 and 4 percent, and Michigan red-shifted less than 2 percent. Similarly, Minnesota blue-shifted less than 2 percent.

Changing "Close %" to 2 will display the following map:

As indicated by the title, the "Close %" value of 2 also colors those states for which the exit poll margin or the final vote margin was within 2 percent. In this case, Ohio and Georgia were within 2 percent Republican in the exit poll and shifted further right in the final vote. In Ohio, the red-shift was severe, between 8 and 10 percent. New Hampshire, on the other hand, was Democratic in the exit poll and red-shifted within 2 percent in the final vote.

Comparing Other Polls and Election Results in the 2016 Presidential Election

FiveThirtyEight has the margins for its polls-only forecast for the 2016 Presidential election posted at this link. It is possible to view the difference between these polls-only forecast margins and the actual final vote margins in the Shiny application at https://econdata.shinyapps.io/voting_538/. Go to that URL and make the following changes:

  1. Under "Races, x & y axes", select "President_538" and "President".
  2. Set "Year x-axis" to 2016.
  3. Set "Year y-axis" to 2016.
  4. Ensure that the first "538 Model" is set to "_polls".
This will display the following page:

The numbers in the MARGIN1 column above match the 538 polls-only margins. Clinton1 and Trump1 were created to match those margins and add to 100 percent since those values are not posted. The last column contains the shift from the polls-only margins to the final vote margins of 4 states that the prior Thom Hartmann article mentioned (Florida, North Carolina, Pennsylvania, and Wisconsin) plus Michigan. These are the same states that "flipped" when using the exit polls in the prior section except that a blue-shift is no longer detected in Minnesota. This is because, unlike the exit polls, the pre-election polls projected that Minnesota would go Democratic.

Clicking the Plot tab will display the following plot:

In the above plot, the x-coordinate of each point is equal to the state's margin in the polls-only forecast. The y-coordinate is equal to its margin in the actual vote MINUS its margin in the polls. Hence, the y-coordinate is the SHIFT in the margin from the polls to the actual vote. On both axes, the positive direction is defined to be more Democratic. Hence, the plot shows that the margins of all 18 of the red solid-Republican states red-shifted with all but 2 (LA and MS) red-shifting more than 5 percent. All but 2 of the 14 solid-Democrat states blue-shifted but all but 3 of those 12 blue-shifted less than 5 percent. More importantly, 5 of the 6 toss-up states red-shifted (AZ, FL, IA, NC, OH), 7 of the 9 lean-Democrat states red-shifted (ME, MI, MN, NH, PA, VA, and WI), and all of the 4 orange lean-Republican states red-shifted.

In the triangle bordered by the y-axis and dashed line and below the x-axis are the 4 states mentioned in the Thom Hartmann article (FL, NC, PA, and WI) plus Michigan (MI). The polls-only forecasts of these states were Democratic but they shifted so far right as to be Republican in the final vote.

Clicking the Map tab will display the following map:

As can be seen, the states that were above the x-axis in the prior plot are shaded blue indicated that they "blue-shifted" to be more Democratic from the polls to the final vote. Most were relatively small blue-shifts between 0 and 4 percent except for CA, IL, NY and, visible in the prior plot, HI and DC. All of the other states are shaded red, indicating that they "red-shifted" to be more Republican from the exit poll to the final vote. ID, ND, SD, TN, and WV red-shifted between 12 and 16 percent.

Changing the selection for "Map Variable" from "MAR_SH" to "FLIP" and ensuring that "Show flips" is checked and "Close %" is zero will display the following map:

The map now colors only those states that "flipped" between the polls and the final vote. The map shows that Wisconsin red-shifted 6 to 8 percent, Michigan, North Carolina, and Pennsylvania red-shifted between 4 and 6 percent, Florida red-shifted less than 2 percent.

Changing "Close %" to 2 will display the following map:

As indicated by the title, the "Close %" value of 2 also colors those states for which the poll-only margin or the final vote margin was within 2 percent. In this case, Ohio and was within 2 percent Republican in the polls and shifted further right in the final vote. In Ohio, the red-shift was severe, between 6 and 8 percent. New Hampshire, on the other hand, was Democratic in the polls and red-shifted within 2 percent in the final vote. Finally, Nevada was Democrat and within 2 percent in the polls but blue-shifted further in the final vote.

Comparing Exit Polls and Election Results in the 2004 Presidential Election

An online document titled History of the Debate Surrounding the 2004 Presidential Election contains a section on page 6 which describes an online article titled The Unexplained Exit Poll Discrepancy. This article was written by a University of Pennsylvania political scientist, Dr. Steven F. Freeman, and contains the following:

Freeman made the point that exit polling was a mature art and that elsewhere in the world, exit poll numbers were used as an independent check on the accuracy of government vote counting. He tabulated the exit poll discrepancies in 11 "swing" states that had been identified early in the campaign as crucial to victory for either party. The discrepancies indicated a broad Kerry exit poll overestimate nationwide, but were significantly higher in these 11 states. Freeman established that the difference between exit polls and official results could not be chalked up to a statistical fluke.

Table 1.1. of the article contains the exit polls from the 11 "swing" states. A table containing the exit polls from all of the states can be found in Appendix B of an online paper titled Analysis of the 2004 Presidential Election Exit Poll Discrepancies. It is possible to view the difference between these exit poll margins and the actual final vote margins in the Shiny application at https://econdata.shinyapps.io/voting_538/. Go to that URL and make the following changes:

  1. Under "Races, x & y axes", select "President_538" and "President".
  2. Set "Year x-axis" to 2004.
  3. Set "Year y-axis" to 2004.
  4. Ensure that the first "538 Model" is set to "_exitpoll".
This will display the following page:

Columns 2 and 3 match the exit polls in Appendix B and the last column contains the shift from the exit poll to the final vote margin for 4 states that flipped from going for Kerry in the exit poll to going for Bush in the final vote. These 4 states were Iowa, New Mexico, Nevada, and Ohio (IA, NM, NV, and OH). Following is the entire table:

Clicking the Plot tab will display the following plot:

In the above plot, the x-coordinate of each point is equal to the state's margin in the exit poll. The y-coordinate is equal to its margin in the actual vote MINUS its margin in the exit poll. Hence, the y-coordinate is the SHIFT in the margin from the exit poll to the actual vote. On both axes, the positive direction is defined to be more Democratic. Hence, the plot shows that the margins of only 11 of the 50 states plus DC polled were more Democratic in the final vote than in the exit poll. These 11 states were Hawaii, Kansas, North Carolina, North Dakota, New Jersey, New York, Oregon, South Dakota, Tennessee, Texas, and Virginia (HI, KS, NC, ND, NJ, NY, OR, SD, TN, TX, and VA). Montana and Wisconsin had identical exit polls and final vote margins. The other 38 became more Republican. This shift to the right has been called the "red shift" as described here.

As previously stated, the dashed line has special significance. It is the line representing y = -x. In this formula, x is equal to Margin1 and y is equal to (Margin2 - Margin1). Taking M to be Margin, the dashed line represents (M2 - M1) = -M1. Adding M1 to both sides gives M2 = 0. Hence, the dashed line basically represents the y-axis of the second race. This means that the points between the solid y-axis and the dashed y-axis are points that, being left of one axis and right of the other, switched sides or "flipped" because of the shift. In the triangle bordered by these y axes and below the x-axis are the 4 states previously mentioned that "flipped" (IA, NM, NV, and OH). The exit polls of these states were Democratic but they shifted so far right as to be Republican in the final vote.

Clicking the Map tab will display the following map:

As can be seen, the 11 states that were above the x-axis in the prior plot (HI, KS, NC, ND, NJ, NY, OR, SD, TN, TX, and VA) are shaded blue indicated that they "blue-shifted" to be more Democratic from the exit poll to the final vote. All were small blue-shifts between 0 and 3 percent except for North Dakota, South Dakota, Kansas, Tennessee. and Texas (ND, SD, KS, TN, and TX) which blue-shifted between 3 and 6 percent. As previously mentioned, Montana and Wisconsin (MT and WI) had no shift. All of the other states that were polled are shaded red, indicating that they "red-shifted" to be more Republican from the exit poll to the final vote.

Changing the selection for "Map Variable" from "MAR_SH" to "FLIP" and ensuring that "Show flips" is checked and "Close %" is zero will display the following map:

The map now colors only those states that "flipped" between the exit poll and the final vote. The map shows that Ohio red-shifted between 6 and 8 percent, Nevada and New Mexico red-shifted between 2 and 4 percent, and Iowa red-shifted less than 2 percent.

Changing "Close %" to 2 will display the following map:

As indicated by the title, the "Close %" value of 2 also colors those states for which the exit poll margin or the final vote margin was within 2 percent. In this case, Colorado and Florida were within 2 percent Republican in the exit poll and shifted further right in the final vote. Their right-shifts were 2.9% and 4.9%, respectively. Wisconsin had no shift, being 0.4 Democratic in the exit poll and in the final vote.
