It's just so weird, he reeks of unmitigated phoniness to the point of bordering on hyper caricature on meth. I always wondered if it's just because I grew up with his constant attention seeking, but his schtick is so irksome.
Even Reagan, as much as I disliked him, I could sense why he appealed to his base so much. Load of bs too, but there was a demeaner, a message, a hook, a personality with a discernible charisma for a certain demographic. He was annoying and chock full of bombastic posturing, but he had that fatherly quality, stern, gruff, seemed like he meant business even if not really.
Trump, on the other hand, makes everyone almost forget what a blithering dunderhead of a tool W was.
