I don't get the dictator for life thing. There are really Americans who want Trump to be permanent POTUS? Seriously? I haven't seen that anywhere but here in P&N, and no corroborating evidence of any kind, no links, no Twitter stuff, etc.
The Atlantic article I linked in the OP makes a clear case that Trump will never admit he was fairly defeated in the election, no matter what, just because of who he is, the nature of his personality disorder. He will/would claim it was rigged, that he actually would have won if this and that hadn't happened and he'll take that to his dying bed and never change his mind... maybe in a delirium he would, but it's doubtful.
His followers? Well, TBH, where I live they don't exist. There are people living 20 miles from me who are Trumpies, but in my town they either don't exist or don't dare come out of their closets.
I will say one thing, though. If Trump through machinations, intimidation, legal wrangles invalidating ballots, etc. etc. manages to steal the election the violence that will ensue will be an order of magnitude greater than the Trumpies will produce if Biden prevails.
