At 7 PM on April 6th, the United States Supreme Court issued a decision on Absentee Ballots:

​

"Under this ruling, in order for an absentee ballot to be counted it must be postmarked by April 7 and received by 4:00pm on April 13th or hand delivered to the polls by 8:00 pm on Election Day, April 7.   Ballots postmarked after April 7 or hand delivered after 8:00pm on April 7 cannot be counted."
