Why? Because Christie shows characteristics of leadership and has a backbone? Let's face it. Obama didn't have a clue about what he was getting into
No, because he's a blowhard who doesn't know how to keep his mouth shut. That shows immaturity and impulsiveness, two things that don't work for the office of the Presidency.
As I said, he has some very good traits. He may mature into a better candidate for the job, but I don't think he's ready now. It has nothing to do President Obama vs. Governor Christie.
