As you see at the brand-new election kwhaertdsheadquarters on times square. Just one day to go, "your voice your vote." The final poll shows a slight edge for president obama, but either man could win a race this close. We begin with david muir covering the romney campaign from cleveland, ohio. Good morning, david. Good morning, george. It's hard to believe it's come down to 24 hours left. On this election eve, several spots for mitt romney. Not surprisingly, one of the key states he'll be in today, right here, the state he needs the most, ohio. Overnight with 20 thousand voters in a state with mitt romney, now looking to broaden his path to that magic number of 270 electoral votes. We're taking back the white house because we're going to win pennsylvania. Reporter: A late play for the future of the state. The campaign telling me they see momentum among independents, swing voters outside of philadelphia. What romney really needs is ohio. The president holding on to a slim but stubborn lead here. Arguing this week with george, it's overstated. When I look at being on the road with governor romney and the crowds and when I look at the undecides, I believe that governor romney could not only win on tuesday, I believe he could win desiefsly. Reporter: Romney said this while in ohio over the weekend. Your state is the one I'm counting on by the way. Reporter: Then there was this on "saturday night live," governor chris christie praised president obama's response to the hurricane. On election day, I'm voting for mitt romney but if I had to pick one guy that had my back in a crisis, it would be barack obama. He's been amazing, so kind, such a leader. Again, I'll be a good soldier, I'll vote for romney, but I'm hate it. You had to know they were going to have a little fun with that bromance in the last week. The romney campaign telling me in the last 24 hours, they're convinced their ground game is well ahead of where it was four years ago. And they've made early inroads, george, they're convinced they're going to take the buckeye state.
