'Super PAC' Continues Attacks on Bain With New Video Faced with a handful of Democrats who have gone off message recently, President Obama's allies on Tuesday sought to shift attention back to Mitt Romney's critics within his own party. A Web video released by Priorities USA Action, a pro-Obama "super PAC," revives the highlights - or, to Mr. Romney, the lowlights - from the extended Republican primary. To his onetime Republican rivals, Mr. Romney was an unfeeling corporate raider whose private equity firm, Bain Capital, was little more than a vulture. "They sit there and they wait until they see a distressed company and then they swoop in and, you know, pick the carcass clean and then fly away," said Gov. Rick Perry of Texas during the campaign. The video strings together similar comments about Bain from Newt Gingrich, Jon M. Huntsman Jr., an adviser to Rick Santorum and Sarah Palin. But will such statements effectively counter the criticism of Mr. Obama from the likes of Cory Booker, the Democratic mayor of Newark? Mr. Booker slammed the president's strategy of attacking Bain Capital, calling it a part of a "nauseating" campaign that is too negative on both sides. Unlike Mr. Booker, whose statement came during an unguarded moment on NBC's "Meet the Press," Republicans delivered their criticism of Mr. Romney and Bain during the heat of the primary. There's no doubt that the Republican criticism was tough - in some cases tougher than what Democrats have said about Mr. Romney and his time at the helm of his firm. The question is whether voters view those criticisms from Republicans as honest assessments, or if they shrug them off as all part of a big political game. If the former is true, then Democrats might gain some traction from using the Republican voices against Mr. Romney. But if voters are willing to give Mr. Romney's former rivals the benefit of the doubt, the Democratic efforts will probably fizzle. There is some evidence to suggest that voters have come to expect intraparty feuds during primaries, and are willing to forgive and forget once they are over. In 2008, Mr. Obama fought bitterly with Hillary Rodham Clinton and her husband, former President Bill Clinton. Mrs. Clinton accused Mr. Obama of "tactics right out of Karl Rove's playbook" and once said he was "perpetuating falsehoods that is not the new politics the speeches are about. It is not hopeful, it is destructive. Senator John McCain of Arizona, the Republican nominee in 2008, tried to use Mrs. Clinton's words against Mr. Obama in an ad that suggested she was not on the Democratic ticket because she was being punished for speaking the truth. In the end, though, the ad did little to help Mr. McCain in his battle with Mr. Obama. Voters dismissed the criticisms from Mrs. Clinton, who later went on to become a loyal member of Mr. Obama's administration as secretary of state. And Mr. Clinton has emerged in the current campaign as one of Mr. Obama's secret weapons. In an e-mail to supporters on Tuesday, Mr. Obama hailed the former president who said such nasty things about him four years ago. "I feel fortunate to have President Clinton on our team today - he's smart, he's tough, and he's committed to strengthening this organization alongside you," Mr. Obama wrote, asking for a $3 donation. Democrats are hoping that using the words of Mr. Gingrich, Mr. Perry and the others will have a bigger impact on Mr. Romney than the clips of the Clintons had on Mr. Obama four years ago. In the meantime, the president's campaign advisers are hoping to keep their own troops more in line.
