But a fuller examination of the comments shows that, in fact, the Democrats are getting their talking points together on the tricky subject of Bain's record in private equity, in which some businesses it got involved in succeeded and others failed.
When asked about Bain's ethics, Senator Warner avoided the question, asserting simply that the company was "very successful." Then Warner, himself a wealthy former businessman, sought to draw the distinction between the private sector and public service.
"I think they got a good return for their investors," Warner said of Bain. "That is what they were supposed to do. I think that when you’re in public life, though, what you’ve got is a different time horizon."
In government, he said, “you’ve got to invest for the long haul."
"My view of private equity is that it is set up to maximize profits, and that’s a healthy part of the free market," Obama said. But the role of president is different, he continued. "My job is to take into account everybody, not just some," he said. "My job is to make sure that the country is growing not just now, but 10 years from now and 20 years from now."
Mr. Rendell, who is also former chairman of the Democratic National Committee, did call Obama campaign ads attacking Bain’s role in a failed Indiana company "very disappointing." But he also echoed another point Obama made Monday: "I think Bain is fair game, because Romney has made it fair game," Rendell told Buzzfeed. He also said he admires Booker, but wished the Newark mayor had qualified and framed his comments better.
