The presidential race in Virginia remains tight, and undecided voters hold the key to the outcome, according to a new statewide poll conducted for The Roanoke Times.

Democrat Barack Obama holds a slim lead over Republican John McCain as both candidates make a final push to win Virginia’s 13 electoral votes. Obama is making an all-out effort to become the first Democratic presidential candidate to carry Virginia since 1964, but the latest poll suggests he has not closed the deal.
