Conservatives are hammering House Speaker John Boehner over the purging of reliably limited government Republicans who weren’t afraid to buck the GOP leadership. But what about Paul Ryan?

There were two Republicans on the House Budget Committee – chaired by Ryan – who voted against Ryan’s budget last spring: Rep. Justin Amash and Rep. Tim Huelskamp. Amash and Huelskamp were just kicked off the Budget Committee, which Ryan is going to continue to chair.

Now consider this quote from an unnamed House GOP leadership aid as reported by The Hill: “Changes are made for a variety of reasons, most often at the request of committee chairs.” That makes it pretty clear that Ryan played a role – if not the role – in getting rid of Amash and Huelskamp. Yet – to my knowledge – conservatives haven’t trained any of their fire on Ryan.

How come?
