(CNN) - Jon Huntsman is now a former Republican presidential candidate. And, like former Minnesota Gov. Tim Pawlenty who dropped out after a poor showing in the Iowa straw poll last summer, Huntsman is endorsing Mitt Romney.
Never mind that Huntsman said some negative things about Romney during his unsuccessful campaign. Pawlenty had coined the phrase “Obamney care” when trying to link Romney’s Massachusetts health care law to President Barack Obama’s health care law. But Pawlenty quickly forgot about that and supported Romney on the campaign trail.
