COLUMBUS -- Sen. Rob Portman predicts Ohio voters will narrowly choose Mitt Romney to get the state's 18 electoral votes.
He says there's more enthusiasm and energy than four years ago.
"I see it in rallies. I see it in the Get Out the Vote efforts. We've made three times more phone calls this year and 20 times more door-knocks," Portman said.
He believes the undecided will break 2 or 3 to 1 for Romney.
"The key issue is going to be how people feel about the economy and whether they are looking for some change," Portman said.
"With undecided voters, there's a frustration about the economy and the debt and they're definitely looking for new ideas. That's what Mitt Romney's offering."
Portman spent Election Day in Columbus.
He knows if Romney narrowly loses Ohio, some pundits will say that proves he should have made Portman his running mate.
Portman brushed aside such talk.
