Perry is a good guy. However, I do not see how he can overcome his enormous gaffes in 2012.
That is my worry - and yes, I fully supported Perry for personal reasons, then phone banked for Newt when Perry dropped out and endorsed him. People might forget, the media never does, and will drag the gaffes and that stupid rock thing up again and again.
The personal reasons? I met him once. Was in Austin, feet hurting like hell, sat down on the steps of the capitol building. He comes out with some of his staff, on his way to somewhere, stops, and asks me if I am OK. A little thing, but it was important to me.
