A Corrupted Election

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.

The U.S. voting system is more vulnerable to manipulation than most Americans realize. Technologies such as electronic voting machines provide no confirmation that votes are counted as cast, and highly partisan election officials have the power to suppress votes and otherwise distort the count.

Exit polls are highly accurate. They remove most of the sources of potential polling error by identifying actual voters and asking them immediately afterward who they had voted for.

The exit polls were based on more than 70,000 confidential questionnaires completed by randomly selected voters as they exited the polling place. The overall margin of error should have been under 1 percent. But the official result deviated from the poll projections by more than 5 percent—a statistical impossibility.

The pollsters report that the precincts were appropriately chosen for sampling, in that the aggregated official results from the sampled precincts accurately reflected the official statewide ballot counts.

In saying this, Mitofsky and Edison vindicate a key piece of their methodology—the representativeness of their samples. If the fault indeed lies with the exit polls, the range of possibilities for error is therefore narrowed.

Finally, they report that the source of error is, in fact, within-precinct error (WPE), the difference between official precinct tallies and the exit poll samples from those same precincts. On average, across the country, the President did 6.5 percent better in the official vote count, relative to Kerry, than the exit polls projected.

This admission further narrows the range of possibilities. If the polling data are accurate, the only remaining possibilities are "non-response bias" (i.e., Bush voters disproportionately did not participate in the exit polls) and/or errors in the official tally.

First, the report acknowledges that the discrepancy between the exit polls and the official count was considerably greater in the critical swing states.

Second, in light of the charges that the 2000 election was not legitimate, the Bush/Cheney campaign would have wanted to prevail in the popular vote. If fraud was afoot, it would make sense that the president's men would steal votes in their strongholds, where the likelihood of detection is small. Lo and behold, the report provides data that strongly bolster this theory. In those precincts that went at least 80 percent for Bush, the average within-precinct-error (WPE) was a whopping 10.0—the numerical difference between the exit poll predictions and the official count. That means that in Bush strongholds, Kerry, on average, received only about two-thirds of the votes that exit polls predicted. In contrast, in Kerry strongholds, exit polls matched the official count almost exactly (an average WPE of 0.3).

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.
