“There’s nothing wrong with profit, by the way,” he said. “That profit went to pension funds, it went to charities, it went to a wide array of institutions…I’m going to stand and defend capitalism throughout this country, throughout this campaign, and I know we’re going to get hit hard from President Obama, but we’re going to stuff it down his throat that it is capitalism that makes America strong.”

Several of the GOP contenders have been criticized for waging attacks on Romney that his critics say are liberal, anti-capitalist arguments that will be adopted by the Obama campaign.

But they still criticized the former Massachusetts governor.

“I think there are specific cases where Bain Capital’s model, which was to take over a company and dramatically leverage it with a great deal of debt, made it less likely to survive,” Gingrich said.

And Rick Santorum did his best to remind voters that Romney was part of an elite group that most Americans will never know.

“I believe in capitalism too,” he said. “Not necessarily for high finance, but for the men and women of this country who are out there battling alone in America right now, who have an unemployment rate two and a half times those that are college educated and feel that no party cares about them.”
