Why was that expected when they have so much evidence of widespread fraud?
If the evidence is that good they wouldn't have to appeal or escalate any cases would they?
They'd just be winning the cases.
But time after time the cases are being thrown out, not because states aren't "policing themselves". What does that even mean in the context of a judge making a decision? The judges aren't being asked to overturn state election. They're being asked to toss out mostly trivial numbers of votes for spurious reasons. The judges are looking for evidence of why they should do that and none is being presented.
The straws you are clutching at are getting increasingly small.
