Transcript for Obama Sees Five-Point Bump Over Mitt Romney

With both conventions wrapped both candidates are barn storming through the battleground, and president brs obama has seen the first sign of a bounce. It's "your voice your vote." David muir is in columbus, ohio, with the romney campaign. Good morning, david. Reporter: Hey, george, good morning to you. As you know, that same gallup poll had mitt romney up by a point before the convention, now afterwards, as you point out, the president opening up that five-point lead which is why romney is coming to the battleground today. No republican winning the white house without ohio. Fresh off the new poll numbers, president obama in florida giving a different kind of lift. The owner of a pizza shoplifting the president a foot off the floor. The other registered republican telling the president he voted for him before and will again. The kind of voters that are swayable. Something new for romney after months of hearing this -- we're going to stop on day one. We're going to get rid of obama care. Reporter: Romney says there are parts of obama care he likes. I'm not getting rid of health care reform, of course. There are a number of things i like. One is to be sure that those with preexisting conditions can get coverage. Reporter: The president trying to take the coverage off the job numbers. You already have a deficit, you add a5 trillion in new tax cuts, $2 trillion in new defense spending and somehow, you're going to close the deficit without raising tax on the middle class family. They did not take their arithmetic course. Reporter: George asked paul ryan about that math. The best way do that is show the framework, the outline and work with congress. That's how you get things done. Isn't that a secret plan? No, no, what we don't want is a secret plan. Why not say right now -- because we want to have this -- george, because we want to have this debate in the public. Reporter: And mrs. Romney fighting back against the notion THE ROMNEYs DON'T KNOW WHAT IT'S Like to struggle. It's been a teacher. It's been a kind of cruel teacher. For people to think we don't have empathy because we're not suffering like their suffering is ridiculous. On that answer about health care, we pushed the campaign overnight and they tell us there's a distinction here. President obama's health care requires insurance companies to cover people with preexisting conditions. At the them mitt romney would put it on the state to buy health insurance. That's a key thing that will be debated in the few weeks to go. Thanks very.
