I am not from the US, but I perceive the same problem in my country of residence (and in other countries I know people from).
The main issue I see is that politics became a sort of entertainment. So a more serious politician (the adults in the room, so to say), communicate in a fairly dry, and even careful tone. And that happens because politics is supposed to be a dry and boring subject.
Budgets, policies, et cetera and so forth, all those are dministrative administrative, not something to be decided with emotions.
But that doesn't lend itself well to communication. So what people pay attention to is the far right buffon yelling about white replacement or such bullshit.
