Yglesias mulls Romney's chances. He says the foremost "known unknown here is whether key conservative media figures who supported Romney in the past would still like him today":
I think it’s worth recalling that Mitt Romney won National Review’s endorsement in 2008 explicitly on the theory that he was equally conservative as Fred Thompson and more conservative than the others. Rush Limbaugh also endorsed him. Romney certainly hasn’t become less conservative in the ensuing time, and well-informed elites were prepared to accept him four years ago.
