Sadly Fred doesn't seem to want it- he just doesn't perform, and that doesn't speak well of how he might approach the "big job" if he somehow won it. Huckabee has impressed me every time I see him. He's a guy who will be able to make friends with other world leaders. He also seems like a guy who will do what is right. The Republicans are going to need a strong and DISTINCTIVE candidate, I think, because it's most likely going to boil down to that person or the Hilary. We should not send an ambiguous, glad hander like Giuliani up against her. Huckabee, given the full exposure as the nominee, could give her a race I think.
All of the candidates have at least one position or belief that one can argue with. In this day and age I can't believe that someone would write off a candidate because of one issue (except, of course, the second amendment). You have to pick the person with the most positives because they all have negatives.
