This is a good example of what I believe to be the basic dynamic going on in the US.
Trump isn't really leading this autocratic coup. He's a tool of the people who backed and made up the Heritage Foundation and the like.
None of them want to, for instance, suspend habeas corpus because they actually consider immigrants to be an invading force - that's just rhetoric to stir up the base and provide cover for their real goals.
Both Trump and his handlers want to suspend habeas corpus so that they can imprison whoever they want whenever they want.
But while his handlers want to do it for the standard autocratic reasons - so that they can disappear dissidents and political rivals and the like - Trump wants it just because he's thin-skinned, egotistical, petty and vindictive, and he wants to be able to punish people who piss him off.
So they share a goal, but for different reasons.
That's how we end up with a relatively nuanced coup apparently being led by a delusional moron - the Heritage Foundation and the other conspirators have arranged things so that the toddler in chief can be allowed to basically run free, telling his lies and throwing his tantrums, and it ends up benefitting them.
