He could get destroyed in public's eye same way he got created (well to the extent of actually getting to be a president). The propaganda machine that created him could just as well annihilate him.
He is not the one controlling all the media and more importantly all the internet propaganda.
Still, he did achieve his goal of being a president of US not once but twice. He had to make a deal with the devil to achieve it but he did. And if he was totally incompetent even the devil wouldn't help. And it's not like his deal has cost him much at all so far.
I think there is a good chance he'd know how to skirt the law if he'd start at a lower rung too.
