From the Baltimore Sun:
Th state Board of Elections officials on Thursday ordered the results of Baltimore's primary elections decertified — and launched a precinct-by-precinct review of irregularities.
Linda H. Lamone, the administrator of the State Board of Elections, said officials became concerned when city officials found 80 provisional ballots that had not been analyzed, and an unusually high discrepancy between the number of voters who checked in at polling places and the number of ballots cast. The number of ballots cast at the polls was higher than the number of check-ins at the polls, she said.
Lamone said state officials were working to determine the exact size of the problem. She expected the investigation to stretch into next week.
"Baltimore City was not able to investigate and resolve these issues to our satisfaction," Lamone said. "We are doing a precinct-level review. We are doing this in fairness to the candidates and the voters."
