And may I add, the wringing of hands over the results not being obvious right away is also grossly overplayed. There are a FEW STATES where results might not immediately be obvious, but unless they hide running tallies we’ll have good analysis by the day after.
I will say that allowing postmarks day-of-election is probably a bad design decision. Tell the mail-in voters to put it in a week before, maybe postmark by Friday before.
