Let tge evidence speak.
If the fraud happened (and it sure loks like it) then vote accordingly
And then do not let anyone break the kaw by rioting and destroying
I think the Supreme Court should acknowledge that widespread fraud occurred but that now it is impossible to separate the valid ballots from the fraudulent ballots and thus it is impossible to use these ballots to determine the winner. Therefore the assignment of Electoral Colleges electors should be done by the state legislatures per Article II of the Constitution.
P.S. I wouldn’t bet too heavily that the Republican legislatures would assign all Trump electors. Perhaps it’s better that they don’t and the vote moves to the House of Representatives.
