from the article:
"Brooks, a fierce opponent of Trump who has called for his imprisonment, said it made sense that working-class Americans would flock to a candidate who's waged war on the establishment that's only out for itself, adding Trump was a "monster" and the elites had correctly identified him as such."
So, Trump is a monster, and the rubes who support him are still smelly icky bitter clingers, but he can kinda sorta see why we might not like our ruling "betters". The solution, no doubt, is to figure out who to mollify the folks in flyover country, while Brooks and his fellow "elite" continue to destroy the nation as founded.
You got it—Brooks figured out that morale does not improve from caning.
