Many Americans, however, were suspicious. Although President Bush prevailed by 3 million votes in the official, tallied vote count, exit polls had projected a margin of victory of 5 million votes for Kerry. This unexplained 8 million vote discrepancy between the election night exit polls and the official count should raise a Chinese May Day of red flags.

On Jan. 19, on the eve of the inauguration, Edison and Mitofsky released their report, "Evaluation of Edison/Mitofsky Election System 2004," which generated headlines such as MSNBC's "Exit Polls Prove That Bush Won." But, the report does nothing of the sort. It restates a thesis that the pollsters previously intimated—that the discrepancy was "most likely due to Kerry voters participating in the exit polls at a higher rate than Bush voters." But the body of the report offers no data to substantiate this position. In fact, data presented in the report serve to rebut the thesis, and bolster suspicions that the official vote count was way, way off.

Notably, Mitofsky and Edison unsucessfully try to explain away the fact that, according to their data, only in precincts that used old-fashioned, hand-counted paper ballots did the official count and the exit polls fall within the normal sampling margin of error.
Other report data undermine the argument that Kerry voters were more likely to complete the exit poll interview than Bush voters. If this were the case, then one would expect that in precincts where Kerry voters predominated, the cooperation rate would be higher than in pro-Bush precincts. But in fact, the data suggest that Bush voters were slightly more likely to complete the survey: 56 percent of voters completed the survey in the Bush strongholds, while 53 percent cooperated in Kerry strongholds.
What's more, the exit poll disparity doesn't tell the whole story. It doesn't count those voters who were disenfranchised before they even got to the polls. The voting machine shortages in Democratic districts, the fraudulent felony purges of voter rolls, the barriers to registration, and the unmailed, lost, or cavalierly rejected absentee ballots all represent distortions to the vote count above and beyond what is measured by the exit poll disparity. The exit polls, by design, sample only those voters who have already overcome these hurdles.
