That's the best approach, IMO.
Perry could well fall flat on his face in a week. Personally, I don't expect that to happen, but you never know. Remember Fred Thompson? He's doing reverse mortgage ads on TV these days.
Perry is a sitting Governor. Perry was the head of the Republican Governors Assoc. He has contacts in every state (He wrote an Op-Ed with Nikki Haley less than a month ago)
He has an actual record as an executive to run on. He is not running on personality or on a narrow platform and he hasn't been running for the last 3 years. He's been governing one of of not the most successful states in the union.
He's very different from the other candidates in this regard, even Palin.
Yep... Thompson looked great, had the right positions on paper, and the right image. But he dragged his feet in entering the 2008 Presidential race, and then when he spoke, it was at 50% speed - boring - with a long drawl and clearing his throat every sentence. Thompson was an idea - but it just didn't work out.
