My gut feeling is that next person after him (if he actually gives up office which is in land of wishful thinking at this point) may be worse, and even visibly worse and US folks will still vote for him/her.
I sure hope my gut is wildly incorrect this time, for me, you, and mankind overall.
Of course, but at least there's a realistic, actually used, mechanism for replacing an administration. Impeachment in the US is a complete non-factor, so you can only wait for four years, no matter how bad things get.
