From
http://stones-cry-out.blogspot.com/2004/11/what-went-wrong-with-exit-polling.html:Richard Morin of the Washington Post "informed me that the CNN {exit polls} had been weighted to the election result".
Morin wrote: "The Post was one of the subscribers to the exit polls, like the New York Times, WS Journal, USA Today. We got the results of the final national poll and a few states when it was completed but before it was weighted, so I know that the poll had Kerry up by 3."
"The MIT-Caltech Voting Project, for example, issued a report concluding that the exit poll data were consistent with state tallies and that there were no discrepancies based on voting method, including voting systems. But they used this adjusted data (weighted to the election result) to exonerate the process! In other words, they used data in which the count is assumed correct to prove that the count is correct…"
So Kerry went from +3 in the exit poll to -3 in the election result. Three possible explanations:
1 Election fraud
2 Perhaps Bush voters voted later in the evening than Kerry voters, and perhaps the exit polls didn't properly account for this.
3 Perhaps Bush voters were more reluctant to participate in the exit polls.
Can anyone say anything about 2 or 3 (or 1!)?
