HARRISBURG (AP) – Senior PA elections officials are arguing in a new court filing that handwritten dates on the envelopes that many state voters use to mail in their ballots should not be mandatory. The brief filed with the state Supreme Court on Tuesday says that’s partially because the Legislature in 1968 acted to de-emphasize the importance of dates on envelopes. Some county officials who run the nuts and bolts of vote counting are poised to throw out ballots without the proper dates in next month’s election, while others are expected to count them. The Republican plaintiffs say if those ballots are not thrown out they should at least be segregated during counting.
