ROANOKE, Va. -

With the attorney general's race still too close to call, provisional ballots could determine who wins.

At this time, it's unclear of exactly how many provisional ballots were cast statewide.

A provisional ballot was cast if a voter didn't have ID or showed up to the polls and wasn't registered to vote.

Localities where a provisional ballot was cast must report those to the State Board of Elections to determine if the vote becomes official; a process that could take up to a week.
