All depends on who wins which states. If the right states go to one candidate, or if it looks like it’s headed that way and networks call it, it could all be over early-ish. Remember 2016 being over by the time I woke up in the morning.
When the Led Zeppelin O2 reunion show tickets were sold you first had to get an "access code", effectively through a random ballot, and use that when purchasing tickets. Ticket resale was specifically banned. But the small print failed to ban sale of access codes.
There was a goodly market in the sale of codes.
I know, because I bought a code, for £100 (which turned out to be, in hindsight, very cheap) from someone in the USA.
And it worked. Got a pair of tickets for the gig.
