CHARLOTTE, N.C. -

It was the moment supporters have been waiting for, the speech of the night - President Obama.

From now until election day, it's a race to the finish line -- a race one political pundit says could be decided by the debates.

"This election is so close, nationally, that almost any event could trigger the defection of a couple percentage points of voters or win a majority of the undecided," said Terry Madonna.

There are only 7-12% of voters in that undecided category.

Madonna says that's the smallest percentage of undecideds in a presidential election in modern history.

There are three planned presidential debates, the first one on October 3.

Neither candidate is likely to falter in a major way.

Before debating Sen. John McCain, President Obama was in a heated primary facing off with then-Senator Hillary Clinton.

Governor Romney has already tangled with other Republicans who Madonna says went after him in those debates in an almost extreme fashion.

"Romney's pretty experienced. I doubt that either one of them will be shaken up by the debate- but these debate performances really could make a difference in the outcome of the elections," said Madonna.

As the convention winds down and the television coverage isn't as constant as the last two weeks, many voters will turn to those debates for answers.

Aside from the three Romney-Obama debates, Joe Biden and Paul Ryan will face off in the solo V.P. debated slated for October 11.
