HARRISBURG, Pa. (AP) — The Pennsylvania Supreme Court has dealt a blow to Republicans in the legal fight over the deadline for mailed ballots in the presidential battleground state. The court rejected without comment Thursday a request by Republicans to put on hold its decision to extend the deadline for receiving and counting mail-in ballots. Republicans are now likely to ask the U.S. Supreme Court to block the ruling. The divided Pennsylvania high court last week granted the Democratic Party's request to order an extension of Pennsylvania's Election Day deadline to count mailed ballots. The court has a 5-2 Democratic majority.
