The Frederick News-Post has the story:

Frederick County election workers on Wednesday will decertify the results of the July 19 primary and rescan all mail-in and provisional ballots after discovering an inconsistency in their numbers, state and local officials said Monday.

While preparing for the recount, officials realized “there were more votes in the certified results than the number of counted ballots,” Nikki Charlson, the deputy administrator of the Maryland State Board of Elections, said in a phone interview Monday.

Anthony Gutierrez, deputy director of the county board, said he suspected that about 100 mail-in and provisional ballots in the District 3 race had been scanned twice due to human error.

That’s about 2% of the 4,597 total votes recorded in the race.
