I mean, the guy is pretty crazy but that doesn't mean he is not smart. The same can be said about Trump, the man is certainly not stupid even though he is a bit crazy. I would probably not vote for Mcafee but I still think he is better than a lot of other candidates including Hilary.
Problem is we don't know how "crazy" the guy can get. IMHO officials in the executive branch should at least have some public governance experience.
But who knows, maybe he'd be a better president than Obama and Trump. If not, at least America entertained the world.
