Even if he were convicted on all the charges we have so far, technically, none of them would bar him from office.
He could be blocked from being sworn in by, you know, being in prison, I guess. But the convictions themselves would not be blockers.
What we need is a Constitutional Amendment that bars convicted felons from higher office, and while we’re at it, maybe add an age cap as well. Nobody over 70 for President, Congress, Senate, or Supreme Court.
