I mean he's enriched himself massively from the position of president and the cult of personality around him makes it impossible for other republicans to come out against Trump without losing massive support (because no matter what libs say, the "never Trump" republicans are a myth) . He also apparently kept a book of Hitler's speeches called "My New Order" on his bedside table according to his ex wife. Do I think he gives a shit about being president or the United States? No. But he definitely likes the power and influence it gives him
