Recent challenges to mail-in ballot applications in Philadelphia's suburbs have sparked legal concerns, with the American Civil Liberties Union of Pennsylvania raising objections to what they deem as mass-produced and illegal challenges. These challenges, numbering in the hundreds, question the voter's residence based on a supposed match with a U.S. Postal Service change-of-address database.
The challenges, filed by a supporter of former President Donald Trump in Chester County, are purportedly nonpartisan and target individuals who have moved out of state. However, the ACLU has asserted that these challenges are illegal, as voters can only be challenged on their qualifications to register to vote.
