WASHINGTON--The assault on Mitt Romney's job creation record while governor of Massachussetts continues in an ad released Monday by the Obama campaign for use in nine battleground states. The spot is titled "heard it all before."

The spot comes after Obama was hit with the May unemployment numbers out on Friday--with only 69,000 jobs created and unemployment up from 8.1 percent in April to 8.2 percent in May.

The Obama campaign on the new ad: "Mitt Romney ran for governor of Massachusetts promising more jobs, decreased debt, and smaller government. By the time Romney left office, state debt had increased, the size of government had grown, and Massachusetts had fallen behind almost every other state in job creation. Romney economics didn't work then, and it won't work now."
