As of 10:27, Oct. 10, 3889 voters in an online CNN Quickvote poll "believe Internet rumors that U.S. President George W. Bush was wired during the first debate with John Kerry". At the time, that was 68% of the poll's votes.
Sadly, the other team had their own debate scandal, with Drudge reporting Kerry had probably broken debate rules and secretly brought in something, maybe notes. It was later shown to be irrelevant (it was a pen). The good news was, a number of pro-Bush blogs cast doubt on this report from the very beginning.
NOTE: The CNN link is to their top page. So a new poll will be up in the near future.
UPDATE: 11:30 p.m. The poll changed about two minutes ago, and the percentages were the same, 68% thought Bush cheated. About 9000 votes out of about 15,000 total.
