Fazio says that he is worried Romney will revert to the policies of George W. Bush.

"It scares me to stick the Republicans back in there." Fazio said.

He also added that at this point in the election, he's watching out for mistakes -- because consistency matters.

"I hate saying this ... but I am waiting for a gaffe from one of them to say, 'Oh my goodness, this is the straw that broke the camel's back.'"

Taylor is looking for someone who can corral Congress.

"I think that the president, while it's an important position, is not the problem here. It's the Congress that's the problem," Taylor said. "And you've got to have a leader who is going to be able to abandon their extreme ideas and come together on a compromise on those positions, for instance, the national debt."

Mencher wants fewer anecdotal stories, negative political sparring, and more logic and facts.

"The person who is going to lead the free world is making low blows on stage?" Mencher asked. "That would lose my vote."

And what comes up in the next round of debates could be significant.

"The second and the third debate become more critical in the minds of the undecided voters," Riordan said.

Those debates could bring up some of the more "volatile" issues that weren't talked about Wednesday night, she said.

"There weren't any social issues introduced," which affect important voting blocs of women and Hispanics in swing states like Colorado, Riordan said.

Undecided voters who tend to vote wait until the last minute to cast their ballots, said Jan Leighley, professor of government at American University.

"If you don't have to buy a new cell phone for another month, you probably won't buy it today," Leighley said.

But for Fazio, because of the debate, he says he couldn't vote today.

"If you had me pencil in a vote today, I couldn't tell you who I was going to vote for."
