I have a clue about how people like Trump work. How US works is hardly relevant in this case. He's one of these people who can make the world descend into madness. I live in a country which had one of those behind the eastern border (technically there wasn't a border back then, but you know what I mean), then, about 30 years later, behind the western one. He is a kind of man who can change how countries work. It doesn't mean he will (I'm hoping he'll turn out to be all bark and no bite when the chips are down), but it does mean you have to be terrible careful with one of those in power.
