With the Florida primary in the books and a triumphant Mitt Romney headed out to favorable settings -- like Nevada, Arizona, and Michigan -- loaded with momentum and flush with cash, we would, in ordinary circumstances, be saying that the 2012 GOP nomination is over. Just need to have the votes, count the delegates, and call it a primary season. But we can't quite do that, can we? And the reason we can't is because Newt Gingrich remains in the race. And he's made it clear that he will stay in the race until his spirit is crushed and his body is ground to dust.
