Jamelle is baffled, as am I:

Even with the apparent enthusiasm of Republican elites, Huntsman remains ill-suited for GOP primary voters. Prior to his appointment as ambassador to China, Huntsman was a voice of Republican moderation on issues like immigration, the environment, and gay rights. As governor of Utah, he accepted federal stimulus funds and castigated fellow Republicans for refusing to follow his lead. Before joining the Obama administration, his only attack on the president came from the left, when he complained that the stimulus was "too small." Yes, Huntsman is anti-abortion and pro-gun, but he's been absent from the economic debates of the last two years and has yet to establish his Tea Party bona fides.
