Perry thinks of W as a country club Republican, a politician too willing to work out deals. Bush doesn't think of Perry much at all. The people who want Jesus as a screensaver on every computer in public schools, call women who have had abortions "baby killers," think that being a homosexual is a "lifestyle choice," and are convinced that humans once saddled up and rode west on dinosaurs; these people all made Bush uncomfortable. But Perry loves them. He shares many of their beliefs. They helped elect him governor.
Yeah, I remember all the talk about how religiously moderate Bush was during his presidency. Nope, never heard a single pundit call Bush extreme once.
I shouldn't let this stuff surprise me, but it still does.
