Donald Trump is possibly going to be imprisoned because he's physiologically incapable of not breaking the law. He's quite literally addicted to fraud and abusing any amount of personal, political, or economic power. And a jury of his peers found that one of his rape accusations (out of many more unlitigated) were credible. And, now that he's on trial for fraud in New York, he's literally too stupid to keep his mouth shut and stop threatening witnesses and jury members despite repeated and specific orders from the judge not to.
