Actually, Fineman hinted at this. He basically said, "Lots of folks in the south drive 'em".
Best line of the night, however, was Howard Dean blamed the loss on (drumroll, please) George Bush!
Blaming George Bush after a year is like an adult who blames his inability to hold down a job, or his being an alcoholic, or whatever, on his childhood, like Mommy didn’t potty train him correctly. But as long as the media gives them a pass, they will continue to blame it on Bush. Or Cheney.
