I'm one of the few people that still think this, but I don't think its that far fetched that he could still make a comeback or at least become more of a factor than he is now. That's not very likely at the moment, but I could see him performing well in the debates and he's probably one of the better retail politicians in the field. That could be enough for a strong performance in NH, maybe even a victory there.
I don't see how Chris Christie can win New Hampshire. The establishment candidate generally does well there, and Christie is too liberal for even N.H. voters.
I'm not sure I'd agree with that. NH Republicans seems to be more moderate in comparison to their counterparts in Iowa and SC. Plus, independents can vote in the primary.
Of course, all this is moot unless Christie can manage to turns things around for himself.
