I can't say I trust what most politicians say when it comes to their careers- I felt there was a 30% chance or so he'd run. And if he did, I would have given him a very serious look as I like and respect his moderate views.
For Perry- I laugh everytime he makes a mistake. I despise him. And for the sake of my favorite state did not want him representing us to the world. Romney has yet to win me over, but he also doesn't come off as offensive with his views. Obama, I have mixed views on and can vote for him again if the GOP doesn't produce.
