Do the Exit Polls Indicate Voter Fraud?

Do the Exit Polls Indicate Voter Fraud?

There are two lines of analysis that are typically used to justify the claim that the 2004 election result was somehow stolen by the GOP. The first is various bits and pieces of "evidence"--the precincts in Cuyahoga County, Ohio with more votes than registered voters, the counties in Florida (Baker, Holmes) with huge Bush margins but big Democratic registration advantages, etc.--that supposedly indicate vote tampering. I find this evidence profoundly unconvincing and think Farhad Manjoo and others have it basically right: there's not a lot of there there. Vote tampering does not appear to have happened on the scale necessary to affect this election.

The second line of analysis invokes the now-infamous early releases of the NEP exit poll data, which showed Kerry with a 3 point national lead, solidly ahead in Ohio and also leading in Iowa, Nevada and New Mexico. The reasoning, laid out most clearly in a paper, "The Unexplained Exit Poll Discrepancy", by Steven Freeman of the University of Pennsylvania, is that exit polls are very accurate surveys and highly unlikely to produce the results referred to above by chance if the real world results truly were +3 Bush, etc. Therefore, the reasoning goes, our measurement of the real world (the actual vote counts) must be wrong and the original exit poll results right. Conclusion: there's something very funny going on with this election....
