I'm less interested donald's non tax payments than the fact that he's broke. Clearly there is some fraud going on in his filings, but most of it is hyper aggressive and hyper creative accounting serving a guy who is in branding and real estate, two businesses that allow for those kind of accounting practices.
More importantly, the evidence strongly indicates donald is living on borrowed dollars and borrowed time. Not even his skanky Russian and "'stan" lenders are going to line up to refinance his properties that are bleeding real cash, especially when there is nothing to back up his personal guaranty.
There is a way out of all of this for him, but he has too much hubris and narcissism to take it. In exchange for resigning before the election, he has to negotiate a pardon from the US Attorney in Manhattan. He also has to negotiate a commitment for pardons from the winner of a Biden/Pence election. (The pardon should include his entire family--yes, even Don Jr.) Secondly, he has huge post presidential earning power. The donald numb nuts can't take their eyes off of him, so he should be able to negotiate huge deals with Fox or One America. Or get backing for his own network. (The pardon agreements would have to include language about no incitement.) The book and movie deals would also be huge. Finally, he would have to learn to live like a $100 millionaire and not a billionaire. Maybe netjet instead of his own plane. Maybe three houses instead of ten. Maybe Eric and Don Jr. get real jobs.
I don't think any of it happens because he's a greedy pig. That doesn't mean it shouldn't.
