What happens if Ginsburg passes before the election, but Roberts deadlocks 4-4 and the election is disputed, they clearly wont allow Trump to nominate another judge, so would DC circuit that Obama stacked have ultimate authority and jurisdiction?

I think I figured out the Bombshell in unmasking. Ponder if this were to come out, Samantha Powers has said that she didn't do all the unmaskings that was attributed to her. What if...... Bidens name is on one of these unmaskings......??????????
