Regardless of what happens in the vote counting, President Donald Trump has said he is going to the Supreme Court to ask for... something or other. When he does, he will have to overcome a hurdle of his own making: his claim to have "already" won the election, made during his rambling speech at 2:30am Wednesday. The justices – including the crucial conservatives like Justices Brett Kavanaugh and Amy Coney Barrett – will not like the speech, which puts them in the position of being asked to validate an obviously preposterous claim and an effort to steal the election before all the votes are tallied.
Trump of course didn't specify exactly what he would ask the Supreme Court to do, stating only that the "voting" must stop. But voting is already over. It's vote-counting that's continuing. So it seems reasonable to assume he meant his lawyers would ask for some sort of stop to the counting.
