Jon Huntsman said that "nobody cares" about Sen. John McCain's (R-Ariz.) endorsement of Mitt Romney.

Speaking roughly an hour after McCain, who officially endorsed Romney's presidential campaign, the former Utah governor said the endorsement was irrelevant.

"I love John McCain. John McCain's a war hero. But you know what? Another Dole, another McCain, another establishment endorsement," Huntsman said Wednesday on Fox News. "It will mean zero in terms of any poll improvement for Mitt Romney because this nation is tired of the past. It wants something new."

Bob Dole, the 1996 GOP nominee, endorsed Romney in early December.

McCain endorsed Romney in New Hampshire Wednesday, where Huntsman has staked his campaign's future. He hopes a good showing in the early-primary state will give him the necessary momentum to win later contests. Romney leads in the number of endorsements by sitting and former legislators in the GOP field.

Huntsman said he didn't need the endorsements of sitting members of Congress.

"The last thing I want is 47 members of Congress supporting me, not when I want to go out and fight for term limits for Congress," Huntsman said.

A recent Suffolk University/7News poll found Romney leading in the Granite State with 43 percent of the vote. The poll found Huntsman with 7 percent, down from the last Suffolk Poll, in which he took 10 percent.
