I like Christie. I would love for him to run. However, I'm afraid the primary might destroy him. He either will have to conservatize himself, which will hurt his reputation with moderates as their best hope for the future, or he will stay moderate and be attacked by everyone on the stage. Because he is a star of the Republican party with very little justification at the moment, that could really damage him.
I think he'd be better to wait four years. If the Tea Party loses this election and/or 2014, it should result in a small leftward modification that will leave a perfect opening for someone like Christie. Better to run on the offense than on the defense.
