Clinton praised Obama for cooperating with people with different political views, pointing to his work after Hurricane Sandy with Republican Gov. Chris Christie of New Jersey.
"He knows politics is about people, not about power, not about ideology," Clinton said. "He knows a philosophy of we're all-in-this-together is a heckuva lot better than you're-on-your-own, and not just when natural disasters strike."
Clinton said Obama stopped the sour economy from becoming a depression.
"When Gov. Romney says, oh, the economy's terrible, we left him a mess, he didn't fix it fast enough, fire him, put me in, you say: I'm sorry, governor, but you want to do what we did before," Clinton said.
First lady Michelle Obama will visit Charlotte on Monday, the day before the election.
