Legitimately hard to imagine what minimum 4 years looks like, considering it hasn't been a month.
Do they all get bored and just cease to govern in a few months?
The most frightening angle, which I think has a lot of legitimacy is the Bannon/far right coup idea floated around. They are legitimizing the notion by the day.
They are practically trying to abolish the judicial branch in the first month. Or at best severely undermine, and attack.
