Tha constitution is the basis of law, not law itself. Someone too young to run for president would obviously be unconstitutional, so there is no need to make a law specifically for that. But what you don’t apparently understand is that Trump hasn’t committed any of the things he has been accused of until he is convicted in a court. Regardless of the fevered dreams of the media and the far left, he is innocent of the charges so far. You could be on video robbing a bank, 20 eyewitness to the crime, cash in your possession when arrested, and you aren’t guilty until 12 people on a jury say you are. He can’t be disqualified yet.
