(CBS News) As Mitt Romney tries to reshape his campaign message to focus on the middle class, the pro-Obama super PAC Priorities USA Action is hitting back with an attack on his record at Bain Capital.
The super PAC's new ad revives a specific line of attack employed by the Obama campaign and stars the same disgruntled steelworker featured in an Obama ad in May.
In the new Priorities ad, called "Understands," former GST Steel employee Joe Soptic recounts how he lost his job and health benefits after Bain Capital -- the private equity firm founded by Romney -- purchased and shut down the Kansas City plant. Soptic's wife was ill but could not afford to go to the doctor; by the time she went to the hospital, she was already dying of cancer.
"I don't think Mitt Romney understands what he's done to people's lives by closing the plant," Soptic says in the minute-long spot. "I don't think he realizes that people's lives completely changed."
The ad is part of a $20 million television and online campaign that scrutinizes Romney's business record and its impact on the middle class.
According to Federal Election Commission rules, super PACs are allowed to support a candidate -- as long as they don't directly coordinate with that candidate's campaign. Priorities USA Action said it filmed this ad months ago, independent of any other campaign or committee.
While using the same steelworker in an ad may seem like coordination, it's just the latest example of how narrow the rules are. For instance, as the New York Times reported, some super PACs and the campaigns they support have worked with the same consultants (Priorities, however, doesn't share any vendors with the Obama campaign). Additionally, some super PACs were founded by former aides to the candidates they support; Priorities USA Action, for instance, was founded by former Obama White House officials.
If Soptic's re-emergence means anything, it's that both the Obama campaign and Priorities USA Action see his story as an effective way to counter Romney's pitch to voters.
Romney has sought to cast himself as an effective manager who can turn the economy around using his private sector experience. In recent days, Romney has specifically talked about helping the middle class,. After the Labor Department reported that the unemployment rate ticked up to 8.3 percent in July, Romney called the jobs report "another hammer blow to the struggling middle class."
As Romney has attacked Mr. Obama for his economic record, he's run his own ads featuring working-class, white males. Those ads have criticized Mr. Obama for saying at a campaign stop, "If you've got a business, you didn't build that. Somebody else made that happen."

Blue collar white males, like Joe Soptic and those featured in the Romney ads, could be critical in this year's election in Rust Belt states like Ohio and Pennsylvania. Democrats, and Mr. Obama in particular, have struggled to appeal to that demographic. Recent polls show Mr. Obama performing well against Romney in Ohio and Pennsylvania, but to win Pennsylvania, for instance, he'll have to in working class areas like Pittsburgh.
