Supreme Court Decisions Shape Pennsylvania's Election Ballot Rules

Recent litigation in Pennsylvania has clarified that mail ballots will be rejected if voters fail to properly date affidavits, but voters can use provisional ballots on Election Day if they make mistakes. With 390,000 mail ballots outstanding, many provisional ballots are expected, potentially favoring Democrats. About 35,000 voters may use provisional ballots if they don't return their mail ballots. The handling of these ballots could impact election results and lead to further legal scrutiny.
