COLUMBUS, Ohio (AP) — Officials with the elections board in the county that is home to Ohio’s capital still could not say Thursday how many voters received the wrong absentee ballots while promising corrected replacement ballots will be mailed quickly once the total number is determined.

Some Franklin County ballots had an incorrect congressional race, while others had the correct information but were sent to voters in a different precinct. The Columbus-based elections board has already sent about 250,000 absentee ballots.

The error happened Saturday afternoon when someone changed a setting on a machine that placaes absentee ballots into mailing envelopes, Franklin County elections officials said Thursday.

Replacement ballots will be mailed to affected voters within 72 hours of the board figuring who received the wrong ballots, said Ed Leonard, the elections board director, according to The Columbus Dispatch.

Also Thursday, the Akron Beacon Journal reported that the mailing of more than 1 million absentee ballots across Ohio will be delayed until at least Monday as a private vendor deals with unexpectedly high volume and equipment issues.

The 20 elections boards that hired Cleveland-based Midwest Direct have tripled the number of ballots they need printed because of the spike in mail-in voting during the pandemic, CEO Richard Gebbie told the paper.
