The Pennsylvania Supreme Court has ordered counties within the state not to count undated mail-in ballots after multiple counties said they would.
The order came on Nov. 18 as the commonwealth began a recount process in the race for U.S. Senate. Both Decision Desk HQ and The Associated Press called the race for Republican Dave McCormick, who ran against long-term incumbent Sen. Bob Casey (D-Pa.). However, because McCormick’s lead fell within a 0.5 percent margin, state law required a recount.
