Jon Huntsman's resignation as ambassador to China took effect Sunday, and he's not wasting much time moving toward a presidential run. He formed a federal PAC today so he can raise money and travel, reports Politico. What's more, the former GOP governor of Utah has been meeting with congressional Republicans and strategists, and will deliver college commencement addresses in South Carolina and New Hampshire this month. Huntsman—regarded as a moderate conservative—is expected to formally announce his bid by early summer, writes Jonathan Martin. (More Jon Huntsman 2012 stories.)
