HARRISBURG, Pa. (AP) — With concerns rising in Pennsylvania that thousands of mail-in ballots will be discarded in the presidential election over technicalities, state officials told counties that they cannot reject a ballot solely because an election official believes a signature doesn't match the signature in the voter's file. The new guidance from Pennsylvania's Department of State also prompted the League of Women Voters of Pennsylvania and the Urban League of Greater Pittsburgh to drop a lawsuit in federal court Monday. The groups had sought to ensure that voters have the chance to fix ballots that are either missing signatures or flagged for a perceived signature mismatch.
