So when Trump became President of the US, he exploited loopholes and tore through "traditions" to hold onto and exert his power. I've always heard that the Queen doesn't have any real power and that parliament really calls the shots in the UK, but how much of that is based on the same "traditions" that Trump ignored and how much of that is actual law? I'm just curious as to what would happen if a power hungry maniac became King/Queen and what they would actually be able to get away with.
