A good article by Tim Noah at Slate about the Club for Growth and Arlen Specter:

Noah's point is that the GOP isn't hammering Specter because he's pro-choice. They're hammering him because he isn't sufficiently pro-economic-crisis.
Just another example of the Republican Party's real interests. Which suggests another way of weakening the GOP's "Values" coalition: just demonstrate their real interests. Call them on their bluff. Get the fundies to vote Constitution Party next time (or not vote at all).
