Daily Kos the day after the election:

The assertion by pundits/Bushies that exit polling was 'way off', and thus, exit polls, which showed an easy Kerry victory in both Ohio and Florida, were incorrectly skewed and did not represent the electorate, is completely bogus.
This is disproved in minutes by simply noting the entire rest of the suite of exit polls conducted by AP and distributed to the news media.

Notice, if you will, that states with a narrow or wide Bush margin of victory NOT called Ohio or Florida, project perfectly. Missouri leans to Bush in exit polls, and leaned to him in the vote. Tennessee likewise was favorable to Bush in exit polls, and it showed in the final results with a clear Bush margin of victory. Pick a state, any state, there is not one single exit poll off by more than a few percentage points in any semi-competitive race. Not one.

Except 2. Ohio and Florida, the latter of which has already been "awarded" to Bush, and the former, which appears to nearly be a lock for him as he is up 3 percentage points with 80 percent of the electorate tallied. George Bush's win in each of these 2 states is nowhere near what exit polls suggest. In Ohio, Kerry had a small but noticeable lead with both male and female voters, a rare thing for him as males have tended to favor Bush in this election by a small margin. Likewise, independent voters clearly broke for Kerry, by a 21 percent margin, 60-39. This is not anywhere near the result we are seeing now, and along with Florida, whom I will get to in a moment, it is a clear and blatant sign of voter fraud. I don't use that most dangerous of "F" words lightly, but I must call a wolf a wolf and a sheep a sheep, and this whole setup stinks like Karl Rove after he's ran 15 feet.

... While Mr. Kerry had 6 percent less support from his party than Mr. Bush did, he scored among woman yet again (54 percent of Florida's electorate) by a 52-48 margin, small but important, while losing men (46 percent of the electorate) 47-52, essentially the same margin. Independents, however, broke heavily for John Kerry, favoring him a staggering 60-38 over Mr. Bush. At the very least, this would suggest a very close race, and certainly not the lopsided blowout it turned out to be.
