Unlikely Huckabee third-party speculation

With John McCain's lock on the GOP nomination deflating elite interest in Michael Bloomberg, pundits have to look elsewhere to engage in pointless speculation about third-party presidential candidacies. Bizarrely, Robert Wright suggested on Bloggingheads that Mike Huckabee might run -- an unlikely idea that was immediately squashed by Huckabee's statement today on "Meet the Press" that he would vote for the Republican nominee. It may be a signal, though, that the pointless speculation will now focus on McCain-hating conservatives rather than anti-partisan centrists.
