The Supremes have one silver bullet, but do they dare use it? They could order a new election in contested states, but likely would instead defer to the existing protocol of letting the state legislators call it.
Even if you called for a new election...the screwed up voting lists, the postal issues, and the same exact problems exist. The date of the Electoral College quickly approaches.
Wouldn’t surprise me if the faked-up results lead to a Constitutional Amendment in six months to remove the EC mechanism. They know that they have the fake votes there...so why use them?
