Perry is a CRAPP.... he runs on a Conservative Republican Agenda to Persuade Partisans.
He's an professional politician with a track record of sucking up to liberals in both parties when the wind is blowing that way. But he knows he has to be SEEN as a staunch anti-establishment "tea party" conservative in the eyes of voters in order to win the GOP primary and get elected in Texas. If he were running in Massachusetts instead, he'd be another Romney.
