In Pennsylvania, voting during the 2024 General Election faced challenges with technical issues and mail ballot disputes affecting the process. Cambria County extended voting hours due to software malfunctions in electronic voting systems, leading to confusion and some voters leaving without casting ballots. Across 14 counties, over 4,000 mail ballot applications were challenged, targeting overseas voters and those who failed to update voter registration after mail forwarding. Misprinted ballots in Greenwich required hand counting, further complicating the election process. An investigation in Lancaster County revealed a significant portion of suspicious voter registration forms as fraudulent. These issues underscore Pennsylvania's critical role as a swing state, with its 19 electoral votes potentially pivotal in the Harris-Trump presidential race.
