A political scientist in my country told that Trump doesn't really have a personality, he is just constantly shaping himself to the will of the masses... like without this presidency he would probably just be a meaningless businessman sniffing cocaine all day with Dom Perignon, fucking a bitch sometimes, nothing more really
and now in this age the masses are very dumb and their logic/thinking is very chaotic and very toxic, they are easily manipulated, lots of them don't even know what they want... so... the issue doesn't really need more explanation :D
