That isn't the question. The question is whether election law was broken.
That is one question, but it's not a very interesting question.
If we assume, for the sake of argument, that election law was broken by not allowing poll watchers within six feet from the beginning, what would happen? Is the remedy to throw out votes by mail? That certainly is not going to happen. is the remedy to throw someone in jail? That is certainly not going to happen without evidence of actual fraud. Is the remedy to re-run the election? I doubt it's possible, but it would only be considered if there was evidence of actual fraud that was enough to put the question in doubt to a reasonable observer.
Mark Levin and some other crazy people have said that having discovered an irregularity, let's even say a violation, just for the sake of argument, the Pennsylvania legislature, without the consent of the Democratic governor, could nullify the election in Pennsylvania and appoint a new set of electors pledged to Donald Trump. That suggestion is not only not going to happen, but the suggestion that it might happen is a sign that someone is delusional, or simply lying for the benefit of their viewers.
And to me, that seems about where this election stands right now. There are lots of allegations, but no specifics. Trump has let loose his AG to look for more dirt, although the AG doesn't seem incredibly enthusiastic about the task, in my opinion. Of all the lawsuits and things that have been talked about publicly so far, the only one that appears to have any sort of basis at all is an argument about whether poll watchers were allowed close enough. (People have been saying they were allowed 10 feet away, but I read it was 25 feet prior to the court order.) It is conceivable that they might get a minor win on that one, but they won't get to change any votes, because they haven't presented any evidence that any votes were changed in Biden's favor.
The fat lady has well and truly sung on this one, but I'm sure she has the ability to return for an encore.
