I don't think this guy is going to fade away. He's always been a showman, demanding the spotlight 24-7, but going forward he's going to put 110% of his dollars and efforts into revenge, to do as much damage as possible to all the people, governments and companies that have offended him in the past 4 years. It will be a long list and he'll pour everything he has into the project. He'll also start his own cable "news" network, create a competitor to Twitter, keep control of at least 50% of the conservative voters to support his Q-anon and Trump-named or branded candidates and break as many dishes as possible on the way out the door. Nope, even after his eventual death he'll have family members and companies that will continue to wreak havoc with his perceived enemies. Nope, that "miracle" isn't likely for a long long time. Brace yourself for more.
That’s one possibility. He has been swindling donors to contribute to an imaginary re-election war chest - with no restrictions on how the funds can be spent, because he’s otherwise broke. However, he is going to have to pay a legal team to defend him against some kind of fraud charges, I think it’s tax evasion, in New York.
A wonderful thought ... we've inoculated ourselves against further spread of the COVID president!
