McCain's response ad

From NBC's Domenico Montanaro
McCain is up with a response ad to Romney's negative ad. McCain skewers Romney in the ad -- running in New Hampshire -- using the words of two state papers.

"The Union Leader says John McCain has 'conviction' and 'Granite Staters want a candidate who will look them in the eye and tell them the truth,'" and announcer says, adding, "'John McCain has done that. Mitt Romney has not.' The Concord Monitor writes, 'If a candidate is a phony ... we'll know it. Mitt Romney is such a candidate.'"
