My only hope is that people as morally insane as Trump are rare, and there may be a correlation between his sociopathic traits, and how seemingly incompetent he is.

What this hopefully means in practice is that even though this time around he will surround himself with yes-men over which he will have more control, few of them will be precisely like Trump and so not immune to actual concern for the future, and to Trump's surprise will not all follow his insane ideas without question, as Trump clearly wants everyone to do. He can't rule on his own. He does need some people, and people needing people requires at least a semblance of regard for others.

In this same way, even his stacked Supreme Court I think will still be likely to put America itself ahead of Trump and a victory that would make a mockery of their own institution, the constitution, and just general common sense.

It's only a shred of hope, but one which might enable civil society to survive another Trump presidency, and if we're really lucky, avoid it.
