I don't know what SCOTUS would do about it.
It has to go to the Electoral College first. SCOTUS would say that the state legislatures already have the remedy power to intercede and select their Electors, no matter what happens with voting chaos. Electoral College rules allow for absent states.
SCOTUS will not select the winner. The state legislatures will.

Also,the Federal courts could,unless I'm mistaken,step in if they detect that any voters' 14th Amendndment rights are being violated by a particular jurisdiction's policies regarding the count and/or recounts.
There can be no doubt that Rat Party Headquarters is planning massive chaos in November...and possibly December.ILLary telegraphed that by proclaiming that Plugs should not concede under any circumstances.
The Rats are planning scorched earth in the days and weeks after 11/3.
