Washington (CNN) – For the second straight week, President Barack Obama's re-election team is attacking Republican challenger Mitt Romney's Massachusetts record with a new television commercial.

The Obama campaign announced Tuesday a new ad titled "Number One" will run in the battleground states of Colorado, Florida, Iowa, North Carolina, New Hampshire, Nevada, Ohio, Pennsylvania, and Virginia. The campaign describes the ad buy as "significant."

"When Mitt Romney was governor, Massachusetts was number one. Number one in state debt. $18 billion in debt. More debt per person than any other state in the country. At the same time Massachusetts fell to 47th in job creation. One of the worst economic records in the country," says the narrator in the spot. "First in debt, 47th in job creation. That's Romney economics. It didn't work then. It won't work now."
