I mean, they can ask. I could file a motion with SCOTUS; I won't get it, but there's nothing to stop me from doing that.
But the lower court ruled that the evidence was not up to standard. The middle court ruled ON TOP OF AGREEING WITH THAT that the case isn't even that specific and Rudy appears to be trying to pull some bait-and-switch in the overall argument - higher courts HATE that.
This is not going to happen. The lower court ruled that there's no merit. The middle court turned down the appeal. Chief Justice Roberts is a NOTORIOUS stickler for the rules on which appeals get picked up.
There is nothing left here. It's not going to SCOTUS. It was never going to. Biden won. He won three weeks ago.
