I have three friends who are die-hard Democrats. They were 100% for Howard Dean, and were devastated when he self-destructed (although they don't feel he did). They also HATE Bush with a vengence. They've been up and down with Kerry, and at the moment, are very disgusted with him ("He's not fighting - he's a wimp - he doesn't stand for anything - blah blah blah"). My guess is that they'll still vote for him (no way will they vote for Bush), that is if they ever make it to the polls. The main talk is about not only may Kerry lose, but what damage he's doing to the party. (PS: they would love to see Hillary in '08 - although they would love even more to see Dean resurrected).
Forgot to add - they also love Nader.
