Frankly, I don't think he would have run if Carney and team hadn't gotten disgusted and quit Newt when he went on vacation. Regarding this, someone was quoted as saying, "Rick Perry is the luckiest politician alive."
And Perry credits his wife as a big influence, recently looking him in the eye and telling him he was "too comfortable" and needed to "step up" or words to that effect.
I know what you’re saying. And I know Nita, too. : )
