As he exits the presidential race, Jon Huntsman is expected to endorse rival Mitt Romney.

Huntsman has been one of Romney’s vicious critics on the trail, attacking the former Massachusetts governor on health-care mandates, taxes, abortion, foreign policy — you name it, Huntsman cut a Web video on it.

The former Utah governor’s campaign pulled multiple anti-Romney videos and Web sites off the web Sunday night, but Huntsman attacked Romney so many times that there’s plenty of evidence left online. Here are some of the most damning attacks.

In October, Huntsman called Romney a “perfectly lubricated weather vane on the important issues of the day,” who “has been missing in action in terms of showing any kind of leadership.”

“There’s a question whether he’s running for the White House or the Waffle House,” Huntsman said on NBC’s “Meet the Press” in November, adding, “I don’t know if he can go on to beat President Obama, given his record.”

Campaigning in New Hampshire this month, he told voters, “Governor Romney enjoys firing people. I enjoy creating jobs.”

He told ABC News around the same time that “the American people, the voters, are going to have a hard time finding, I think, a gut level trust when it comes to someone who has been on so many sides of major issues.”

In the NBC News New Hampshire debate, Huntsman criticized Romney for questioning his patriotism “while he was out raising money.”

Just last week, Huntsman called Romney’s “Believe in America” slogan “phony nonsense.”

Some of Huntsman’s anti-Romney Web ads can still be found online.

There’s an ad comparing Romney to a wind-up monkey toy when it comes to abortion.

A similar one comparing him to a weather vane on various issues:

Another ad declared that Romney “led Massachusetts, led them close to the very bottom” and called his job creation record “sadly similar to that of Obama’s.”

As Felicia Sonmez reported Monday morning, tension between the two politicians goes all the way back to the 2002 Salt Lake City Olympics.
