HEMPSTEAD, N.Y. -- Rest assured, the blue cushioned chairs will be taken Tuesday. The rest will be filled with undecided voters.

How Mitt Romney answers their questions could sway who becomes the nations next president.

"We're very grateful to be back at Hofstra. It’s amazing to see the set go up and to understand what is going to take place here," said Janet Brown of the Commission on Presidential Debates.

The town hall will be filled with Nassau County residents. The moderator selects the question from undecided voters from Nassau County who will be in the audience.

Noted suburban expert Larry Levy says those voters tend to be more liberal than others.

Levy said, "The voters in Nassau have the same issues as voters anywhere else, they just have different demands and expectations for their life."

Outside, the signs and political artwork are being arranged. The university of 11,700 students seemed to buzz with nervous energy.

"I think the energy is just crazy," Chelsea Gillyard said.

Hofstra pride is uniting Gillyard, a democrat from the Bronx, and Victoria Rametta, a republican from Connecticut. Both political junkies, they seemed to gawk at how their campus is transforming into the epicenter of the presidential race.

Gillyard said, "A helicopter outside my room this morning. It was pretty loud. It felt like someone was going to come through my window. It was pretty awesome."

Only one thing could make it better.

"Unfortunately, I have not gotten a ticket yet. If I could bribe, if I could buy the ticket off someone I would, but I can't. They are very strict with the tickets," said Rametta.

So who can get in aside from the candidates, the moderator and the undecided voters? There is a lottery for students. Otherwise, Hofstra has set up four watch parties, plus two for the surrounding communities and two for alumni.
