I disagree completely. There are a lot of tweaks which need to be made to the various mechanisms of American government, but ultimately there's no system you can design which can fix the problem of "approximately half the country is in a personality cult to one guy who demands absolute power, and his supporters in government refuse to enforce the law against him". Or at least no system which is remotely recognizable as democratic. How could that possibly work?

It's user error, and trying to fix it without changing the minds and wants of those users just makes them angrier that "the Elites are undermining the will of the People" or whatever.
