“35% of the presidential ballots probably will be cast before election day“:

Early voting is often promoted as a convenience for harried citizens. But it may be a bigger boon for candidates, enabling them to deploy money and personnel more efficiently as they work to corral votes as soon as possible.
“By encouraging our supporters to vote early, we can focus our resources more efficiently on election day to make sure those less likely to vote get out to the polls,” said Adam Fetcher, an Obama campaign spokesman. “We’ve made early investments in battleground states, where we’ve been registering folks and keeping an open conversation going with undecided voters for months.”
….Early voting can insulate a candidate against a damaging gaffe or negative news story in the closing weeks before election day. The disclosure of a decades-old drunk-driving charge against George W. Bush five days before the 2000 election may have cost him as many as five states, Rove, his chief strategist, later wrote. Late damage could be reduced this year, when more than 35% of the vote is expected to be cast early, compared with less than 15% in 2000.
But the dynamic works both ways. Early voting could mute the boost from a positive event — like a strong showing in this year’s final televised debate on Oct. 22, only 15 days before the election.

It might be convenient, but it just doesn’t seem very smart. Who knows what could happen, right? Now, I could see maybe a day or two out (which, according to the story, is when a majority of “early voting” occurs), but even then, who knows? As we’ve learned though, maybe the problem isn’t the “early” part of this sort of voting, it’s the “mail-in” part.
