U.S. Senate race in Virginia extremely close heading into Election Day

Virginians will be keeping an eye on another big race Tuesday night - the race for United States Senate.

Republican George Allen and Democrat Tim Kaine, both former governors of the Commonwealth, spent the final day of their campaigns shoring up last minute undecided voters.

The winner will take the place of Jim Webb, who is stepping down after one term.

Allen's wife, Susan, made a stop at a campaign office in Bristow Monday.

"It's going the enthusiasm we're seeing on the ground," Susan said.

Taking the stage Monday in Sterling at an event for Vice President Joe Biden, Kaine told supporters he is the clear choice for bi-partisanship.

"We can't have the nation we want if the Senate and Congress is gridlocked. We have to fix it," Kaine urged.

The latest NBC News/Wall Street Journal poll taken late last week shows Kaine holding a three point lead, which is very close to the poll's margin of error. The poll says four percent of voters are still undecided.
