with the level of shady electronic voting, i'd say yes.
in 2004 in Ohio, Kerry had a huge lead in exit polls. there was a 1 in 50,000 chance that bush could win the state. Suddenly, the power went down minutes before the results were to be announced. two hours later, after the 'team' came in and fixed it - diebold employees whose CEO had promised to deliver the election to Bush in an internal memo - it was announced that Bush won Ohio by a comfortable margin.
In light of the statistical miracle that took place, the democrats naturally asked for a legal and perfectly normal count of the paper backups to ensure that this miracle was 'on the level'. instead, the republicans sued to have the records destroyed. The republican state legislature decided to lock them up so they couldn't be counted, and to this day, we still don't know who actually won because the lawyers are still fighting for a right to recount them.
One day, these ballots will be counted and they'll likely (49,999 in 50,000 chance) that Kerry won Ohio and therefore should have won the overall. To this day, you hear smug republicans laughing about the 'whiny libs' whose only request is that the ballots actually be counted as is the law. I guess they won't feel that way when Pres Hilary steals the next one from McCain, eh?
