Obama Web ad uses GOP primary opponents to bash 'Romney economics'

The commercial opens with a Romney appearance on Fox News, where he declares, "I'm pretty proud of a very conservative record, and that record will stand up to virtually anyone else running in this race."

Onscreen text then declares that "other Republicans don't agree," leading to a montage of prominent Republicans criticizing Romney's record on job creation as governor of Massachusetts.

Among the Republicans featured: Newt Gingrich, Rick Perry, Rick Santorum, Jon Huntsman and, from the 2008 GOP primary, Sen. John McCain (R-Ariz.).

The ad primarily focuses on claims that Massachusetts ranked 47th in the country in job creation during Romney's tenure, but also includes candidates hammering Romney over increases in taxes.

"Mitt Romney claims his business experience will grow our economy, the same claim he made when he ran for governor of Massachusetts. But Romney Economics actually plummeted Massachusetts to 47th out of 50 states in job creation, increased debt and expanded government for the people of Massachusetts. Don’t take our word for it — just ask his fellow Republicans," the Obama campaign said in a statement.

The Obama campaign has made a push this week to highlight Romney''s record in Massachusetts, with senior adviser David Axelrod appearing at an event outside the statehouse on Thursday.

“Romney economics didn’t work then and it won’t work now,” Axelrod said.

The Romney campaign issued a statement Friday criticizing Axelrod's appearance.

“President Obama continues to launch desperate attacks because he has no positive record or accomplishments to run on,” wrote spokesman Ryan Williams in a statement. “If President Obama had even half the job-creation record of Mitt Romney, then he would be running on it.”
