So I'll add because I'm more or less with you: I'm sincerely confused how we can spend years alleging Russian interference and now that on a really close election, with contention over the way the ballots were counted, it's being called by the media without presenting doubt despite polling being pretty off? The inconsistency is concerning, in my opinion. What am I not understanding?
If I'd introduced a new system in at work (my understanding is the mass mail-in ballots are new at this scale, but please correct me if I'm wrong) and was testing it and it gave a weird result, I'd at least double check it.
