I suspect if what has transpired doesn't make them concerned, they will only be emboldened.

It does not work like that. Look at countries with similar leaders, past or present: they remain popular. The masses don't experience an epiphany.

They won't. This is the same line of people that voted for Reagan and Bush II. I used to be one, most of my family still is. Whatever Democrat gets elected (if we have reasonable elections) will get the blame from them and it will be used to fuel the election of the next populist.

This is the mistake a lot of people made with Bush II and Trump I, thinking that "this will all go away" when the man at the center goes away. It won't, no man rules alone, they represent a large population of anti-intellectual isolationists who are not going anywhere. At best you can hope that the intellectuals will govern in a way that helps everyone next time they get a chance, leaving less fuel for the next populist wave.

Would you enlighten us about how we are supposed to feel in 2.5 years?

Very, very happy, or else

The killings will continue until morale improves?

Well, the beatings didn't work, did they?
