I think this is the crux of it. He is incompetent, yes, he wears diapers… he’s functionally illiterate… definitely a 2 digit IQ… BUT he is also a sociopath. In a room full of other, smarter, sociopaths he gets manipulated easily. In his world there has never been any concept of black and white truth because there has always been someone there to curate his reality. To be honest, he’s a perfectly constructed politician.
