Not controversy, RINO idiocy. The only reason the GOP has a majority in the House, and therefore Boehner is Speaker and not Minority Leader, is that the Tea Party drove re-taking the House in 2010. Boehner and RINOs are attacking the very people who put them back in power in the first place.
Why is it a big deal that McCarthy prepared the list? Was it expected that Boehner wrote it himself?
