I'm starting to get interested in Christie. He's rising in the polls the hard way, by changing his underlying favourability numbers (i.e. not just increasing his vote share by increasing his name recognition as Carson and Trump did) from
46% favourable to 64% favourable in New Hampshire, and the more I see of him the more I like. The first video is particularly good.
You can disagree with the content of his message but you can see from audience response that he's got some game when it comes to relatively moderate Republicans. The question is, are there enough of those left in America?
Ed: obligatory Nate Silver counterargument:
