Twenty-seven hundred Lancaster County voters who requested mail-in ballots for the May 18 primary election received a ballot packet that incorrectly informed them that they did not need to add postage to the return envelope. The Lancaster County Board of Elections became aware of the error on Saturday, said Christa Miller, the boardâs chief registrar. Unlike in the November 2020 election, Lancaster County voters are required to pay the postage to return their ballots in the mail. Voters can avoid paying postage by placing their ballot in the drop box located in the Chestnut Street entrance to the county building at 150 N. Queen St. in Lancaster city.Â
