Perhaps more to the point, Trump has been telling people that he will announce a run for the 2024 presidency as soon as the vote is certified for Biden. This would keep money flowing into his pockets, as well as keeping him in the news. Sources have told Maggie Haberman at the New York Times that the president has no grand strategy other than to keep his supporters energized to follow him into whatever he does next, including, perhaps, launching a competitor to the Fox News Channel.
Even his niece has said that he would never risk losing like this again as of today. If he's prosecuted and he loses, he will become even more insignificant. This descent is the worst thing that he can imagine. Drumming up money helps in that he'll need it and it's his attempt to keep him relevant. His followers will discover in time or not but it will become apparent to anyone truly seeing that he is a shallow, self-centered narcissist who doesn't care about anyone other than himself.
