(CNN) - Two Virginia political heavyweights on Sunday said the presidential race in the Old Dominion, a crucial battleground state, would come down to a nail-biter.
Sen. Mark Warner, a Democrat, and former Rep. Tom Davis, a Republican, each argued on CNN's "State of the Union" that his party's candidate would carry the state - but they agreed the final results will be close.

Davis, who served as a seven-term U.S. congressman, said Romney is on an "upward trajectory."
"It's close, but Obama's turnout model is going to be down from 2008. The kids are not coming out for him like they did before," Davis said, referring to the youth vote that helped Obama win the state four years ago for Democrats for the first time in four decades.
Warner, however, said the president has a significant advantage over Romney among women in Virginia, an important voting bloc needed to win the commonwealth. He cited the bill passed by the Republican-controlled House of Delegates and signed by Republican Gov. Bob McDonnell that requires women to have an ultrasound before having an abortion.
The senator also argued the Obama campaign was better equipped in Virginia than its rival. "Going into the last two weeks, we've got twice as much operations in place in Virginia than the Romney campaign."
A recent American Research Group poll showed Romney ahead of Obama by one percentage point in Virginia, 48% to 47%. The survey was conducted before the second presidential debate last week.
With the race being so close, Warner and Davis both acknowledged that third-party candidates in the race could have an impact on the final results. Constitution Party candidate Virgil Goode, Libertarian Party candidate Gary Johnson, and Green Party candidate Jill Stein will all be on the ballot.
Goode, who's from the state, in particular may pull some votes away from Romney, but Davis said he's not too concerned about a potential spoiler.
"He probably cuts into us more than the other side, but he's just driving around the state in his truck," Davis told CNN chief political correspondent Candy Crowley. "I think our lead's going to be big enough to overcome that if we get our vote out. "
