The ad and Huntsman's comments are an aggressive push by the Huntsman campaign to capitalize on recent criticism Romney has fielded from conservatives for being inconsistent on certain issues. Recently, Huntsman was attacked for appearing to reverse his position on the Ohion union measure. On Tuesday Romney refused to say where he stood on the bill.
A day later he said he fully supported "Gov. Kasich's Question 2 in Ohio."
"I'm sorry if I created any confusion there," Romney said.
Also on Friday, Huntsman's daughters released a spoof campaign ad based on an unusual spot from Herman Cain's presidential campaign. Cain has been competing closely with Romney to lead the Republican presidential field in the polls.
