Missouri Rep. and Senate Candidate Todd Akin made controversial comments about rape on Monday.

“If it’s a legitimate rape, the female body has ways to shut that whole thing down,” he said.

Akin backtracked on Tuesday but still refused to quit his race.

“I used the wrong words in the wrong way and for that I apologize,” he said.

His decision to remain in his Senate race defied Republican party leaders, including Mitt Romney, who issued a statement Tuesday.

"[Tuesday,] his fellow Missourians urged him to step aside, and I think he should accept their counsel and exit the Senate race,” the statement read.

But Democrats noted Republicans officials put forward an anti-abortion party platform Tuesday that makes no exceptions for rape or incest, though Romney has made clear he does support such exceptions.

President Barack Obama, meanwhile, hammered Romney on higher education Tuesday, telling Ohio college students Romney would cut student aid to fund tax cuts for the wealthy.

“His economic plan makes one thing clear. He does not think investing in your future is worth it," Obama said. "He doesn’t think that’s a good investment. I do.”

Democrats released an ad mocking Romney’s advice on paying for college, playing a statement from Romney that said “the best thing I can do for you is tell you to shop around.”

But it wasn’t just Romney’s words being used against him. His running mate, Paul Ryan, dredged up an Obama quote from the 2008 campaign.

“Remember this other time where he was caught on video saying people like to cling to their guns and their religion?" Ryan said. "Hey, I’m a Catholic deer hunter. I am happy to be clinging to my guns and my religion.”

Wednesday, Obama is back in New York City, where Michael Jordan, Carmelo Anthony and other basketball stars will help him raise campaign cash.
