HBO "Real Time" host Bill Maher writes on the Tea Party Republicans attempting to purge the GOP of moderates in Congress:

What’s missing from this equation is pushback. Republicans have been worse than moderate Muslims in standing up to their radicals, even the ones who are actively calling them names. They smile and mutter about “big tents” and “diversity of viewpoints” and secretly sh** themselves over being primaried, and very few have stood up and said, “Really? A ‘traitor?’ That crap is out of bounds, you nutjobs.”
