@hawkeye10,
But what he does is to be elected as Governor of Texas. That's really regional. George W. Bush parlayed it into something bigger but he had Yale and the fact that his DAD had been VP for eight years under Saint Reagan and President for four.
Perry is a Bush-caricature in terms of good-ol'-boy-ness and doesn't have those (rather important) mitigating factors.
He's getting beaten by Obama by 11 points in polls now, and that's when people already know everything there is to know about Obama. Perry is coming off of the personification of "none of the above" phase and people aren't getting more impressed the more they see him. (He was being beaten by 7 or 8 points earlier.)
I don't know how much more time the Republicans have to enter a new "none of the above" avatar. Christie might do it, but Palin is already too well-known to really fit, there.
So, even though he's fading, Perry might be the last one to slide in, and he could win the nomination.
Which would be really, really good news for the Obama administration.
