Sure. We had Nixon.

Most collapses start slow, and I tend to doubt this one is finished.

I expect things to actually get better by some measures for a little while as the U.S. liquidates its holdings of international political and socioeconomic influence. A sort of short-lived glut from voluntary cannibalization.

There a quite popular narrative saying JFK's murder was a coup, and the US is still couped to this day (voting does not truly matter: the dark budget agencies make the policies anyway, those votes into office simple have to follow suit).
