I think there are several who are pretending to be conservative as hell, but aren't. They tickle the ears of their voters, knowing full well they will have the votes within their ranks to stop whatever conservative bill they say they want to pass. It might end the political career for one or two Republicans, but it protects their institution. It also allows them to scream even louder. Oh, and the sacrificed Republican that votes against them? Golden parachute, and a nice ride off into the sunset.
