Even if he wangles a federal pardon, I think New York is going to prosecute him, and I think the IRS and Deutschebank are going to collect their money. So he's going to end up pretty poor, if not bankrupt. New York State has no reason not to prosecute. Trump went out of his way to kill a whole bunch of their citizens with his pandemic decisions, and I'm not talking about even-handed general policies. He directed funds and equipment toward his Red State friends and away from New York and California, resulting in actual deaths. Why wouldn't New York prosecute any of his New York crimes? Tax Fraud and Bank Fraud at the least. Maybe Money Laundering, too.
I doubt he will end up at Mar-A-Lago, except as a paying guest, because he will lose it in the bankruptcy or foreclosures.
