The only thing that separates Trump from the likes of Hitler was the incompetence you describe so well in this article. Making enemies of the people you need within the security apparatus shows how brain dead the man is, as does hiring people like Sidney Powell and Rudy Ghouliani.
One more thing separates him: At heart, the man is too much of a coward to try to truly pull it off. He's a fascist wannabe, just a part of his carnival barker personality.
But don't underestimate the damage he has done. He has made basic, unarguable facts a contest. He has set the stage for the next potential fascist, who won't be so damn stupid, will have genuine charisma that appeals to a broad audience instead of just a subset of people, and will have the brains to know how to command the security apparatus to do what he wants it to do.
