Romney has been Kerryed. He's done. You can smell it through the way he talks that he's a talented used car salesmen running for president.
McCain really intrigued me when he said "radical islamic extremism" for the billionth time. Scaring votes works but not when its all you've got.
Huckabee found the populism missing in the other candidates and has an opening. His policies are also good enough for many conservatives, but different enough that he can run on the change ticket.
Thompson knows best, or else you'd think it by the way he talks. Tries to play the tough conservative but people can see right through it, remember that ad he ran smoking a cigar and responding to some stupid comment somebody made? Go get 'em, Fred.
Guiliani's strategy might work because the party is so fractured, but he doesn't have the same appeal that usually puts Republicans in the White House.
Right now I see Guiliani being able to win strategically (no clear winner in the other states and he goes on to steal Florida and some others), but Huckabee is performing better. Even with the absurd mistakes he has made, Huckabee knows how to sell it when he is on.
