It always seems to happen: Whenever Rick Perry needs a break, he gets one. As the weekend begins, his terrible perfomrance in a New Hampshire speech has gone viral. The video is shown on Leno, on The Daily Show, everywhere. Perry is a national laughingstock. And then comes the news that Herman Cain was accused of improper behavior while he was head of the National Restaurant Association, and suddenly the Perry video is off the front pages and Cain’s campaign is taking on water, and blaming Perry for leaking the story. The leaker isn’t the story. The leak is the story. And Perry’s goofiness is forgotten.
