As expected, New Hampshire went solidly for Romney, with two libertarians placing and showing. The race's social conservatives didn't fare to well (although if you count Ron Paul's racism as social conservatism, you could say that certain types of social conservatism are still acceptable to the New Hampshire electorate). The tenor of the race will change considerably when the candidates head into traditionally backwards South Carolina, where clear thought is generally seen as anti-American, and who better to know anti-American than the state that started a war with America.
You have to wonder how Ron Paul's flavor of politics will play in South Carolina. On the one hand, he hates the government that he's served in for about half his life, so that's a plus. On the other hand, he's a staunch isolationist who doesn't believe in crusading American Empire, which won't play well with those who think we're in a clash of civilizations.
A few months ago, Rick Perry may have done well in South Carolina, but his campaign is such a painful thing to watch that even his base surely must have weighed their options and realized that Santorum is actually a more coherent candidate. You know you're in trouble when you make Rick Santorum seem like the better candidate.
Speaking of Santorum, I think it's good that he and the others stay in the race as long as possible, bruising Romney and letting the general public see the wackiness that passes for Republican thought. It's a narrow rainbow, but it's very vibrant, from Santorum's musings on "man on dog" sex to Ron Paul's cloud cuckoo land dreaming.
