Election officials in the District of Columbia and Prince George's and Montgomery counties are warning a large number of absentee and provisional ballots could delay final results in tight races.
Provisional ballots are subject to review by the elections boards, and those votes won't be counted tonight. Elections officials carve out days to make sure each provisional vote is valid.
In Washington, thousands of provisional ballots are expected to be cast. The most heated race being decided is that for mayor where incumbent Adrian Fenty is trying to fend off a challenge from D.C. Council chairman Vincent Gray. The winner of the Democratic primary will likely become mayor. The D.C. Board of Elections will rule on those provisional ballots on Sept. 22.
In Prince George's County, elections officials will reconvene Thursday to tally absentee and provisional ballots.
Montgomery County officials also estimate they could receive between 2,000 and 5,000 provisional ballots. Those will be counted on Sept. 22.
