Pennsylvania’s top court has ruled that mail-in ballots marked with the wrong date will not be counted.
In a victory for Republicans ahead of the midterms, the court said such votes would be set aside and preserved.
Democrats and Republicans are deeply split on mail-in voting. The issue gained prominence after a surge in the 2020 election caused by the pandemic.
Republicans fear postal voting benefits Democrats, even though data suggests both parties are affected equally.
About 70% of the 1.4 million requests for mail-in ballots in Pennsylvania this year come from Democrats, compared to 20% from Republicans.
