I find Christie to come across as hostile, emotionally fragile and going out of his way to annoy conservatives. He's overcompensating for some issue.

That is my impression of him as well. I couldn't vote for him either. He didn't want to sign with the other states on the Obamacare lawsuit. Wouldn't have taken much for him to get involved either. I thought his over the top, slobbering affection for Obama after the hurricane was the final straw. I'm not saying he shouldn't have been thankful for the government help, but it was a BIT much.
