I'll go first. I figure it might go one of two ways:

1) There is no winner announced on Election Night. It will take days, weeks, or months to determine a winner. This gives them enough time to manufacture enough votes to put Harris over the top and she is eventually crowned the winner. They sentence Trump and Harris pardons Trump as a peace offering to throw him and his supporters a bone. The Republicans retain the House (and possibly take the Senate) so Harris gets little done.

2) Trump wins decisively and it's announced on Election Night. The Dems instead focus on manipulating a few of the down ballot races, just enough to take either the House or Senate in order to (figuratively) handcuff Trump. There is so much focus on Trump that there would be little outrage as the Dems take Congress instead. They still try to sentence Trump, block his certification, try to impeach, etc. Trump gets little done.

Those two outcomes prevent armageddon, which realistically isn't in anyone's best interest, keeps the fire burning (which generates a lot of revenue especially for media companies) and limits any "damage" the President can do. The powers that be might even be wary of Harris getting too uppity and trying to implement some of her most left leaning ideas.

I may be completely wrong, but not expecting either side to run away with it.
