I like all of those except Landrieu & Clinton. I just think Hillary brings more negatives than positives to the ticket and undercuts his message of change & judgment on Iraq.
I like Wes Clark, but he was pretty terrible at campaigning in '04. He's probably gotten better since then because he's been all over the place for the past 4 years...but I don't know if he would bring Arkansas (his home state).
Granholm is actually unpopular because of Michigan's struggling economy, I think, but it's moot anyway.
