PHILADELPHIA (AP) — A federal appeals court must decide if Pennsylvania voters who put the wrong date on the envelope containing their mail-in ballots should have their votes thrown out. The case argued Tuesday in Philadelphia could be significant in this year’s presidential contest. The NAACP and several voter groups call the mistakes “meaningless” and want them counted. They say that more than 10,000 ballots in the state were rejected in 2022 over mistaken dates. Republican groups are challenging a federal court ruling last year that the votes should count if they are received in time.
