My main disagreement, is that it puts too much blame on Trump.
The Republican party had already taken a turn toward evil, long before Trump got into politics. I've been seeing the Republicans as "unfit to govern" for around 30 years. But, arguably, it started before then, when they went with "the Southern Strategy" to use racism as a core, albeit unstated, principle.
The Republican Party went for a Faustian bargain. And that, in turn, allowed the party to be co-opted by Trump.
