On March 1, the U.S. Supreme Court refused to hear two cases filed by Republican candidates for presidential elector over the November 2020 election returns. Bowyer v Ducey, 20-858, is from Arizona; Feehan v Wisconsin Elections Commission, 20-859, is from Wisconsin.
There are still two more November 2020 election returns cases pending in the U.S. Supreme Court. They are on conference for March 5, and are from Georgia and Wisconsin.
I suspect that the majority on the court is going to ignore election cases or issue really bad opinions on election law.
