Supreme Court order could affect Pennsylvania Senate count The Supreme Court on Tuesday temporarily blocked the counting of some mail-in ballots in Pennsylvania, an order that could affect the tight Republican Senate primary between former hedge fund CEO David McCormick and celebrity heart surgeon Dr. Mehmet Oz. An order from Justice Samuel Alito paused a lower-court ruling in a lawsuit over a disputed 2021 local court election that would have allowed the counting of mail-in ballots that lacked a handwritten date. Based on that ruling, the state had advised counties to count those ballots in the race between McCormick and Oz.
