Yup.
And assuming we don't straight up lose our democracy, we're at least going to experience a long period of decline, possibly lasting the remainder of our lives.
This isn't going to magically change 4 years from now, even if the pendulum swings back and we vote Democrats into power. Our society just proved itself to be utterly uneducated and intellectually lazy. We're just going to keep digging ourselves into a deeper hole. And that's assuming in the next 4 years Republicans don't change things in such a way as to ensure they can never lose an election again.
One way or another, we've lost. The only question is the speed at which the decline will take place.
