HARRISBURG (AP) – The PA Supreme Court is weighing in on a flash-point amid ongoing vote counting in the U.S. Senate election between Democrat Sen. Bob Casey and Republican David McCormick. On Monday, the court ordered counties not to count mail-in ballots that lack a correct handwritten date on the return envelope. It’s a win for McCormick as the campaigns prepare for a statewide recount. Casey’s campaign says the ballots should not be rejected for garden-variety errors, like a polling place worker forgetting to sign it. Republicans say the law is clear that the ballots must be discarded. The Associated Press called the race for McCormick, concluding that not enough ballots remained to be counted in areas Casey was winning for him to take the lead. As of Monday, McCormick led by about 17,000 votes out of almost 7 million ballots counted.
