(CNN) - Former Utah Gov. Jon Huntsman isn't letting up on his barrage of Mitt Romney-aimed insults. A web video released Thursday is the latest of Huntsman's efforts to paint the former governor of Massachusetts as a serial flip-flopper.
The spot opens with coverage of public criticism toward Romney for changing positions. The news clips are followed by video of the GOP frontrunner addressing the issues of immigration and abortion where he appears to reverse his stance–over a period of time. One clip reflects a younger Romney, compared with some from the current campaign.
"12 million are still here illegally, should be able to sign up for permanent residency or citizenship," he says in one clip.
But in another, "We can't talk about amnesty; we cannot give amnesty to those who have come here illegally."
And the video closes with Romney in his own words, "I'm sorry if I created any confusion in that regard," he says.
Huntsman, also a former U.S. ambassador to China, has consistently polled in low single digits of support since announcing his candidacy in June. He's spent most of his time in New Hampshire with hopes of a good showing in the state's critical first-in-the-nation primary. Huntsman's latest jab at Romney is well-aimed as Romney holds a big lead in recent New Hampshire polls.
