I understand why he thinks that - hear me out.
The guy is a total fuck-up. Incompetent in business, disgusting personality, no grasp of science. He's so stupid he doesn't even know how stupid he is.
But Americans fucking love him. They send him money, they give him power. They fucking made him PRESIDENT. Yeah, they made the gasbag who played a tycoon on The Apprentice PRESIDENT!
Of course he thinks that all his good fortune must stem from something innate. Americans have gaslit this cunt into thinking he is a genius. Trump is the victim of advanced American stupidity.
