Don't underestimate the powers of the executive branch. If the Dem's win clearly win the Presidency, and the court tries some end around, the Executive branch is going tell the Judicial Branch it's sanctions have just been voided. It will be a crisis, but one the court will lose. But it wouldn't be 5-4, Trump would lose 7-2. Alito and Thomas are that insane, I don't believe the other 3 are.
