I think Chomsky nailed it as far back as the nineties, at least. I cannot find the exact quote, but he was commenting on the "Angry White Male" thing and said that of course a great many people had the right to be angry about their situation, but that of course they'd be pointed at the wrong things/people either as deflection or as the (false) cause.
When people say that the cons manifested donnie vs. donnie somehow coming along and changing the cons, they are not wrong. It's no coincidence that donnie is glued to grievance outlets like Faux and just repeats their bilge. When these angry people have been eating up Faux nonsense and a candidate comes along that just repeats everything on those grievance outlets, and gives them a permission structure to start saying some of the worst thoughts they have out loud, it's all too obvious who they are going to vote for.
Naturally, that candidate will be doing absolutely nothing for them beyond their feels and will most likely just enact policies to make their situation even worse.
