According to the exit polls conducted by Edison Research, Clinton won four key battleground states (NC, PA, WI, and FL) in the 2016 Presidential Election that she went on to lose in the computerized vote counts. With these states Clinton wins the Electoral College with a count of 306 versus 232 for Trump. Clinton also won the national exit poll by 3.2% and holds a narrow lead in the national vote count still in progress.

Exit polls were conducted in 28 states. In 23 states the discrepancies between the exit polls and the vote count favored Trump. In 13 of these states the discrepancies favoring Trump exceeded the margin of error of the state. See Table and its footnotes below.

November 14, 2016: As requested by a few people attached is the zip file (very large at 5,300KB) containing all the exit polls downloaded from CNN shortly after the polls closed in each state. If using these files please credit  and Theodore de Macedo Soares as the source and most importantly cite the article that shows the results of the exit polls:

November 17, 2016: The table below was updated to reflect the most current vote counts. Electoral College count updated to include states not previously decided. Michigan results will not be formally decided until the end of November but as it is expected that Trump will win its 16 Electoral College votes it has been noted as a Trump win. Electoral College results calculated with the interactive map at

The exit poll vote proportions for Clinton and Trump were derived from the gender category (all the other categories would have the same result). Clinton’s proportion of the male vote was multiplied with the total male proportion and added to Clinton’s proportion of the female vote multiplied with the total female vote to arrive at Clinton’s vote share in the state. The same procedure was applied to arrive at Trump’s proportions of the exit poll vote.


[1] Exit polls (EP) conducted by Edison Research and published by CNN shortly after the closing of state polls and downloaded by TdMS. Edison Research conducted one national EP and EPs in 28 states. As these first published exit polls are altered/adjusted to conform to the unverified computer vote counts, the discrepancies shown above are adjusted to near zero in the final EPs.

[4] Note that the Margin of Error (MOE) is for the differences between the two candidates (at 95% CI). This MOE is about double the usual MOE for each candidate. MOE calculated with multinomial formula discussed in sections 2 and 4 in: Franklin, C. The ‘Margin of Error’ for Differences in Polls. University of Wisconsin, Madison, Wisconsin.
