A Quinnipiac/New York Times/CBS News poll showed the president leading Romney by 10 percent among likely Ohio voters.

In Bedford Heights, a suburban of Cleveland, Romney received a helping hand from the host of Discovery's "Dirty Jobs" when appearing at American Spring Wire, according to USA Today. Mike Rowe had a few words to say on the importance of manufacturing, although he came short of actually endorsing the former Massachusetts governor.

"We have unintentionally disconnected ourselves ... from the most important part of our workforce," Rowe said.

Romney took questions from business leaders and audience members, vowing to take a tough stance against China over its currency manipulation, according to CNN.

"Ultimately the engineering and high end things go where the manufacturing is because ideas and engineering are associated with manufacturing," Romney said. "We have to have manufacturing here and my policy will be to bring it back."

China has been a recurring theme for both candidates as they try to gain the support of voters in the industrial Midwest. Obama worked to bolster his already widening lead over Romney in the Buckeye State on the campus of Bowling Green State University.

Speaking in front of a crowd of college students, Obama dismissed Romney's "new-found outrage" against China, as he accused his opponent of profiting from jobs sent overseas to China during his time at private equity firm Bain Capital, the Wall Street Journal reported.

Obama also critiqued Romney's plan to cut the deficit and lower taxes.

“No matter how many times they tell us they’re going to reboot their campaign” and explain Mr. Romney’s tax plan, Obama said. “They can’t. They won’t.”

Romney has made 19 previous trips to Ohio, which is almost certain to be a must-win contest for his campaign in November. No GOP candidate has ever captured the White House without winning the state.
