They cannot get a mulligan. The duty of the court is to protect every voter in the state. If I voted for Trump and there were no shenanigans in my county and my vote was erased by fraud I am just as much a victim as any Biden voter in that county if they toss an entire county. I do agree that would be justice, but courts would be reluctant to do it.
I agree with all of you that there is only one constitutional answer and that is for the legislature to appoint the electoral voters, but politicians don’t like to do stuff like that. They could “legislate” a remedy.
If Biden fights it he tells the world he knows the results would not favor him. The status quo is going to create a huge mess.
I do think the legislature could do it if they thought outside the box. The courts would have to respect it also because it even gives them an out as well. It removes most of the blame from the Governor, legislature, and the courts.
I think a re-vote would violate US Law, which sets the date for Federal elections...
