VIRGINIA (WUSA9) -- After a grueling election night, it's been a long day of counting vote after vote, and voter after voter.
Vote canvassing is a mandatory ritual made even more important by tight races like the still undecided Attorney General Race between Republican Mark Obenshain and Democrat Mark Herring.
"One million votes cast for each candidate. It comes down to a handful of votes cast. You never know what's going to happen," said Brian Schoeneman, the Secretary of the Fairfax County Electoral Board.
He says they are checking over tapes that recorded votes from both the touch screens and optical scanning machines, making sure there are no errors. He says occasionally, a worker records the numbers wrong.
The Electoral Board is also deciding whether to count about 480 provisional ballots those are cast by people who were not listed as registered voters at the precinct where they arrived. A few of those people have already come in to plead their case.
Herring's campaign is urging anyone who cast a provisional ballot to go in to the Electoral Board and defend it.
Canvassing is to be over by November 12 and the county's results sent to the State Board of Elections.
After the State Board of Elections certifies the results on November 25th, a candidate who loses by one percent or less has ten days to request a recount. In the Attorney General Race, it's certainly close enough at this point to expect a recount.
