When Trump leaves office in January, he will be facing an avalanche of legal problems, including civil suits, potential criminal charges in New York, and a variety of investigations initiated by the House of Representatives. What impact, if any, will that have on his potential candidacy?
Not as much as you might expect. If there is one thing we learned from his four years in office, it is that his trusty base couldn’t care less about allegations of misconduct; they just view it as another form of disruption, and thus a promise kept. Furthermore, we know that the allegiance of his base alone is enough to win him the nomination, if not a general election. In short, nothing that comes out of any investigation over the next few years is going to cost him the nomination, if he wants it, unless he winds up doing time in New York, which is unlikely.
The more pressing question is whether his physical and mental health will permit him to run at an even more advanced age. On that point, I make no predictions.
