Very well said, and so true
Then along comes Trump who says to them ‘you screwed up, have been incompetent, and we need to get better qualified people in place to fix things’. He challenged their stature, told them and the world that they weren't doing a good job (e.g. ‘Fake news’, ‘poor negotiation of trade deals’ etc.), pointed out their hypocrisy and incompetence, and basically treated them as obstacles to a great future for America - not the elite deciders of that future that they see themselves as. He essentially treated them with the same derision and ridicule that they have for years treated ‘fly over country’ with. He exploded their myth of superiority, and they hate him for daring to challenge them, and they hate us for voting for him and for being supported by him.
