I think his biggest problem, politically, is that he talks like someone who's spent most of his adult life as a Washington insider, circa 1990s, and doesn't know how to "bring tha crazy" the way that the talk radio/Tea Party faction of the party likes it. Yes, a man who spoke in a political interview about "man-on-dog sex" isn't crazy enough for the modern Republican Party. Ponder that. And, at the end of a day, Santorum is a man who wears out his welcome -- his 59 percent rejection by Pennsylvania voters in 2006 was the highest I've ever seen for an incumbent senator not facing corruption charges.
