Mitt Romney may be significantly ahead of Jon Huntsman in the polls, but he’s been needling Huntsman this week. At a 4th of July parade, Romney welcomed Huntsman — no stranger to New Hampshire, where he has been actively campaigning — to the state where Romney owns a vacation home, and alluded to Huntsman’s service as President Obama’s ambassador in China. Two days later, the Romney campaign sent out a list of endorsements from politicians in Utah, where Huntsman served as governor from 2005 to 2009.

Today, the Huntsman campaign blasted a list of Massachusetts (where Romney governed, of course) Republicans who support Huntsman, including former Senate nominee and Massachusetts GOP chair Jim Rappaport and John McCain fundraiser Peter Malone.
