Nearly the entire point of the United States at its founding was that the law should apply to political leaders. We are overdue for setting the precedent of a former President being charged with a crime, and we ought to go back and charge a few other former Presidents with crimes while we’re at it.
I'm 100% in support of applying the law to all people. What I don't love is the timing of it. It makes it easily dismissible as political theatre. Wait until after the election.
If you treat your life as one big show, any accountability will seem like theater, but that doesn't mean you get to avoid it.
