Obama heads to battleground Ohio facing tough race

Biden began the second day of a three-day swing through Ohio in Toledo, and the president will return Thursday evening for a rally in Cleveland. GOP running mate Paul Ryan will speak Wednesday at Cleveland State University, with Romney scheduled Thursday to be at a Cincinnati machine and manufacturing plant that also produces military components.

"You're going to see Romney and Ryan in the state a great amount," Jennings said. "It all underscores the importance of Ohio. It may well be (Ohio voters) who decide who is the next president of the United States."
