My dream scenario is that late votes after deadlines, including the usual late arriving dumps of unverified mail-in ballots, are strictly enforced.
Heck, “Haiti-hole” countries do it. Why not the USA?
Best scenario?
Counting would never be suspended, for any reason.
If you announce a suspension, a leader MUST be announced.
Either campaign can sue for an injunction on further counting.
(It’s entirely possible that Trump could do that now; I’m not certain of all the States rules on that.)
