Republican slouching?

Current reading: Republican Gomorrah: Inside the Movement that Shattered the Party, by Max Blumenthal. It's a leftist view of the religious right. As I'm not a fan of leftists or the religious right, it'll probably leave me with some mixed emotions. But we'll see. I note that it opens with a discussion of R.J. Rushdoony, whom I'd long thought of as a fairly marginal (albeit deeply reprehensible) figure. (Walter Olson wrote an eye-opening article about Rushdoony and his Christian Reconstructionism for Reason back in 1998.)
