On November 22, three Washington state Democratic presidential electors filed this reply brief in Chiafalo v Washington, 19-465. This is the case over whether a state can punish “disobedient” presidential electors. This is the final brief for the Washington state presidential elector case. The next step in this case is for the U.S. Supreme Court to set a conference date to decide whether to hear it.
IMO, a state can fine an elector for breaking his or her pledge, but they cannot remove and replace him if he has cast his vote.
