Christie will have to act like a fringe lunatic, but still won't survive the primaries. He hugged the Kenyan. He took the Kenyan's FEMA money. He betrayed our rightful mormon overlord right before the election.
He may win in some places like, Vermont or Maine or New Hampshire, but he will uniformly be clobbered in the south. And, he's catholic. The south also hates them some catholics.
Which is fine. He's not as awesome sauce as the national press makes him out to be. The only reason he's successful here is:
1. he's a crass big mouth. Jersey loves crass, big mouthed fatsos. Mainly because Jersey is full of them. The south loves fat louts too, but not the kind with NY-ish accents.
2. the NJ democrats have a very rigid hierarchy, a political machine, in which every dem in the state has to stay in line or be exiled from politics. So Christie does not have to wrangle with a senate and congress. He only has to wrangle with one or two top Dems and they get the rest of the party to line up. If Christie has any actual skills in that regard, he's not had to use them.
2a. because of the rigid hierarchy, NJ democrats do not breed competent political leaders. They promote supporters, who do not campaign very well in the big elections. This is why Christie is projected to win by about 20 points in a fairly blue state.
