It's not that it looks like one; it's that it is one.
People have been working since the sixties to make it one.
Once you've got a plurality of the population (and a majority of the white settler population) who think it's illegitimate, it just is. That's the definition of a failed state, even before you get into the "institutional armed groups who are not subject to civil control" and "widespread terrorism" and "institutional authority not accepted" (for example, Congress not enforcing subpoenas because collectively they can't imagine that they're allowed to do that.)
So, yes, people voted for Trump; they're voting to legitimise the state they believe in, which is a white ethnostate where there are no facts. ("Educational divide" is excessively abstract; the complaint is that facts are those things that reduce their social status. You cannot imagine how intensely they're against facts.) This is why conspiracy theories are popular; it's a way to explain why what they want is necessary.
Lots of people did NOT vote for Trump. They're voting for what they believe in, which includes notions of legitimate collective action, limits to profit, and a cosmopolitan inclusiveness that accords rights to everyone. Thing this groups has not figured out is that the other group is incapable of admitting error, so traditional political processes involving compromise don't produce improvements to the circumstances.
I keep hoping they're going to learn.
