Well you're right about that. Trump was the first and hopefully last American president to attempt to steal a presidential election. He was also our first mob boss president. We've never had a former president facing 91 criminal charges. And he's only the third president, to my knowledge, to have committed crimes while in office.
Richard "I Am Not a Crook" Nixon, was in fact, a crook. He didn't want to be prosecuted. Ford didn't want him to be prosecuted. They both knew Nixon wasn't immune from prosecution. That's why Ford pardoned him.
Bill Clinton lied under oath. That's a crime. He was worried about being prosecuted, he knew he could be prosecuted, and he knew he wasn't immune from prosecution. That's why, hours before his term ended, hours before he became Citizen Clinton and would lose the protection of "you can't prosecute a sitting president," he cut a deal with independent counsel. He admitted he gave false testimony under oath, he agreed to a five year suspension of his law license and he paid a #25,000 fine in exchange for an agreement by the independent counsel not to indict him.
In sum, the only two other presidents (besides Trump) who committed crimes and faced criminal prosecution knew full well that they did not have immunity from prosecution. Neither does your boy.
