New Obama ad hits Romney record in Mass.

The Obama campaign is back with another ad in Pennsylvania and eight other states, and back to hitting Mitt Romney's record as governor of Massachusetts.

"First in debt. Forty-seventh in job creation. That’s Romney economics. It didn’t work then. It won’t work now," it says.

The spot is running in Colorado, Florida, Iowa, North Carolina, New Hampshire, Nevada, Ohio, Pennsylvania, and Virginia.
