In an intensifying legal battle over the voting process in Pennsylvania, the Republican National Committee (RNC) has filed multiple appeals to the U.S. Supreme Court, seeking to block the counting of provisional ballots and challenge mail-in voting rules. This comes amid a ruling from the Pennsylvania Supreme Court allowing voters to cast provisional ballots if their mail-in ballots are rejected due to defects. As local officials work to address issues with mail-in ballots, Republicans are pushing for a halt to what they describe as erroneous counting practices, arguing that certain provisional ballots should be disqualified. The situation reflects a broader national debate on voting regulations as local and state courts become crucial battlegrounds in the lead up to the upcoming presidential election.
