President Obama's campaign will air yet another ad attacking Mitt Romney's business career at Bain Capital, this one in the swing states of Ohio and Virginia.

The ad has already begun airing in the Youngstown, Ohio media market, according to Kantar Media's Campaign Media Analysis Group, which tracks political ads.

In it, a narrator says:

When Mitt Romney led Bain, hundreds of plants, factories and stores were shuttered. Workers saw their wages slashed, their jobs sent overseas. Romney made a fortune. Now, he wants to bring that business experience to us. He'd keep tax breaks for outsourcing and hand new tax cuts to millionaires, all while raising taxes on the middle class. Romney's not the solution, he's the problem.

The Obama campaign and its allies have hammered Romney for his business career, a significant part of the credentials Romney's campaign has touted.

Obama for America memorably aired this ad on reports that Bain-Capital-owned firms were involved in outsourcing. The pro-Obama super PAC Priorities USA Action produced a controversial ad insinuating Romney's activity at Bain led to a woman's death, after a factory closed-an ad that has been criticized by fact checkers.
