Just saw a nice Legal Eagle video about the upcoming election and the probable lawsuits.
And the key seems to be the provisional ballots being counted or not. So to be safe, Harris needs to win by a margin much bigger than the provisional ballots. Then it would be hard to really call into question the votes and to certify or not.
By that, I mean by Jan. I'm sure there will be a ton of election workers who will be forced to just do their job, since it's NOT their job to find reasons to not do their job. Multiple workers faced charges before for refusing to just do the job they are assigned to. And I'm sure there will be a source of lawyers who ignore the repercussions laid out on the 2020 lawyers when they lied in court. So there will be confusion, chaos, and things talked about. But of all of that, the only ballots that seem to really be capable of being questioned are the provisional ballots.
So if Harris/Walz wins by a wide enough margin, then the courts will have no genuine way to overturn the election. The SCOTUS will just have to make it up, and then it will be a battle between them and Biden/Harris.
BTW, I think I have google spell checker, and for some reason, it thinks Walz is a misspelled word. I'm not going to add it to the dictionary, as it should be automatically done.
