I heard Christie was being vetted for the VP slot and was confident he’d be chosen but after the European trip last summer Mitt chose Paul Ryan instead. Supposedly Christie is miffed by this and it also explains why Christie mentioned Romney so seldom during his convention speech. Supposedly he is a sore loser.
I do not believe that for a minute. Christie made it clear he did not want to run as VP...He said he was not ready to do so and he wanted to finish his term as NJ Gov. I do not know how much more clear he could have made it. Pretty clear to me.
And if you look into why Christie didn't make the VP cut, it was because of his unpredictability and self-serving nature. A President shouldn't have to keep looking over his shoulder to see if his VP is undermining him.
