Executive Summary:
  • There is a substantial discrepancy—well outside the margin of error and outcomedeterminative— between the national exit poll and the popular vote count.
  • The possible causes of the discrepancy would be random error, a skewed exit poll, or breakdown in the fairness of the voting process and accuracy of the vote count.
  • Analysis shows that the discrepancy cannot reasonably be accounted for by chance or random error.
  • Evidence does not support hypotheses that the discrepancy was produced by problems with the exit poll.
  • Widespread breakdown in the fairness of the voting process and accuracy of the vote count are the most likely explanations for the discrepancy.
  • In an accurate count of a free and fair election, the strong likelihood is that Kerry would have been the winner of the popular vote.
