Just as the finishing touches are made in the debate hall and the camera angles worked out for Tuesday night's big match-up, it may be hard to believe, but there was a voting line in Georgia -- already -- about three weeks before election day.
One woman in line said "We waited about two and a half hours."
Estimates now that one-third of all voters will cast their votes before November 6, which is why the President's campaign is trying to lock in support now.
First Lady Michelle Obama was seen holding up her absentee ballot.
"Today, I voted for my husband!"
If followers on both sides follow suit in the days to come, that means that any little blip from the debate or the one next week could have an immediate impact.
President Obama ran through mock debates at a resort in Virginia.
Mitt Romney and his debate team, including his sparring partner, Ohio Senator Rob Portman, spent most of the day hunkered down.
Portman said it went "great."
And the town hall format at Tuesday's debate could make a difference too -- with questions coming from uncommitted voters.
"...For challenger Romney what's at stake is to continue the very strong performance that he gave last time and keep the momentum that he has going on right now. The momentum is clearly swinging in Romney's way and so for Obama this is a chance to regain the momentum and stop Romney," said Hofstra University political science professor David Weiden.
