The Obama campaign ramped up its attack on Mitt Romney's record in Massachusetts with a new web video on Thursday, which focused on the former governor's economic results and his inability to translate his private sector experience into job growth in the state.

The video, over four minutes long and titled "Broken Promises: Romney's Massachusetts Record," features a series of clips connecting the promises Romney made while running for governor in 2002 to the statements he has made during his current presidential bid. It focuses in particular on his touting of his private sector experience during both election cycles.

Clips of Romney's earlier promises are interspersed with on-camera statements from a host of Massachusetts leaders, who recall the governor as difficult to work with and failing to live up to expectations. The present and former lawmakers home in on Romney's failed economic record with respect to job growth, reducing the deficit and cutting taxes.

"When Gov. Romney became governor of Massachusetts, many of the issues that our country faces were at our doorstep," says Melrose Mayor Rob Dolan in the video. "High debt, the need for jobs, the need to support a working middle class. There were great opportunities, and there was great hope that Gov. Romney could deliver. He didn't deliver."

The Romney campaign was quick to respond, refocusing the attention on Obama's own record. "The Obama campaign has gone from 'Hope and Change' to 'Hope To Change The Subject,'" said Andrea Saul, press secretary for the Romney campaign. "Only President Obama, who has failed to meet his own goal of 6% unemployment, would have the audacity to attack Mitt Romney's record of creating jobs. We're happy to compare the 4.7% unemployment rate Mitt Romney achieved in Massachusetts to President Obama’s weak record any day."

But for the Obama campaign, this is just the beginning. Obama for America Senior Strategist David Axelrod will hold a press conference Thursday in front of the Statehouse in Boston to discuss Romney’s economic philosophy and his failed economic record in Massachusetts. In similar vein to the campaign's new video, Massachusetts elected officials who served with Romney will appear with Axelrod.

Axelrod also put out a detailed memo Wednesday evening titled "Romney Economics: It Didn’t Work Then And It Won’t Work Now," delving further into the Republican presidential candidate's history handling the economy while presiding over Massachusetts.
