HARRISBURG Potentially thousands of mail ballots requested by Butler County voters appear to be lost, a county official said Wednesday, and the U.S. Postal Service has been asked to immediately investigate what happened to them.
A USPS spokesperson, meanwhile, said the agency is unaware of any significant delays or issues and is in regular contact with the Board of Election as we work to locate and deliver ballots as they are presented to us.
As of Tuesday, Pennsylvania voters are no longer able to apply for an absentee or mail-in ballot.
Nearly 40,000 registered voters in the county requested mail ballots. So far, only 24% of them have been returned to the county, by far the lowest rate among the states 67 counties. The county with the next-lowest return rate, Fayette, has received 50% of requested ballots.
