- An ABC News/Washington Post poll out earlier this week showed that 13 percent of voters remain undecided, making them a critical part of tonight's debate audience. 

The third and final presidential debate between Barack Obama (web|news|bio) and John McCain (web|news|bio) comes as most polls show Obama with a widening lead; however, with one in 10 probable voters still lacking a favorite it is still anybody's game.

"I think I know, but then I watch the debates and get confused; I watch the news and get confused," said Montez Wilson, an undecided voter. "I'm very excited about tonight."

Montez is hoping to hear more about health care and the economy in tonight's debate. And like other undecided voters, she is looking for specific differences between John McCain and Barack Obama.

There is one thing most all voters can agree on: they don't want to hear any personal attacks. "I don't want to hear mudslinging. I want to hear what they are offering the country and then judge it from there," said Maureen Sturgill, another undecided voter.

In battleground states, like Virginia, undecided voters know they are coveted and critical in this final leg of the race.

"We do live in Va., so I feel my vote is going to really be counted this year," said Tareq Rashidi, an undecided voter.

As a result, many undecided voters are hoping to be able to make a decision after Wednesday's debate.

"I need to hear exactly what they're going to do and I need to hear convictions," said Wilson. And when asked what if she will do if she doesn’t here what she wants in tonight's debate, Wilson said, "I don't know, maybe it'll be the last moment when I get there in the booth, I don't know."

After the debate, both candidates will focus their efforts on the battleground state of Virginia with Barack Obama holding a rally in Roanoke Friday and John McCain making a stop in Woodbridge on Saturday.

Virginia has voted Republican for president every year since 1964.
