Obama and Romney campaigning hard for the Ohio vote - KTTC Rochester, Austin, Mason City News, Weather and Sports

COLUMBUS, Ohio (AP) -- Bolstered by a strong debate performance, Mitt Romney is intensifying his efforts in the key state of Ohio. The Republican presidential nominee told a rally in Cuyahoga Falls tonight, "Ohio's going to elect me the next president of the United States."

President Barack Obama also campaigned hard in Ohio Tuesday calling out to students at Ohio State University, "All right, Buckeyes, we need you."

It's the last day of voter registration with Election Day now just four weeks away and Obama's campaign had buses nearby, ready to ferry students or other supporters to registration centers.

There are signs the president's advantage in Ohio is narrowing as a new CNN poll shows Obama leading Romney 51 percent to 47 percent among likely voters in the Buckeye State. Some Republican strategists say the race is even closer.

No Republican has won the presidency without winning Ohio.
