Trump’s second defense will revolve around the element of intent in the various statutes he has allegedly violated. He will argue that he genuinely believed that the election was rigged. He may even go so far as to assert on the stand that, notwithstanding all of the evidence to the contrary, the election was, in fact, rigged. Does that defense have any chance of success?
Smith will be able to put on witnesses who will testify, not just that any number of important people told Trump that he lost, but that Trump himself conceded several times that he lost. Trump can, of course, insist that all of these people are liars. But he is the most notorious liar in the country. He lies as often as he breathes. Smith and his team will have no problem putting that on display if Trump takes the stand, as he must under this scenario.
In short, the answer to the question is no. This is a defense with plenty of danger for Trump, and few prospects of success.
