Obama Campaign Still Hitting on Romney Bain Record

And around it goes.

Priorities USA Action is pressing its attack against Mitt Romney over his work at Bain Capital, underscoring the inroads the "super PAC" has made at turning the Republican presidential challenger's business experience against him.

The group, which was started by two former aides to President Obama, is launching an emotionally charged television commercial Tuesday featuring a former employee of GST Steel, a Kansas City mill that went bankrupt after it was purchased by Romney's private equity firm.
