I don't think David Brooks has reconciled himself to The Donald yet:
Some conservatives believe they can educate, convert or civilize Trump. This belief is a sign both of intellectual arrogance and psychological naïveté.
The man who just crushed them is in no mood to submit to them. Furthermore, Trump’s personality is pathological. It is driven by deep inner compulsions that defy friendly advice, political interest and common sense.
It’s useful to go back and read the Trump profiles in Vanity Fair and other places from the 1980s and 1990s. He has always behaved exactly as he does now: the constant flow of insults, the endless bragging, the casual cruelty, the need to destroy allies and hog the spotlight. “Donald was the child who would throw the cake at the birthday parties,” his brother Robert once said.
It's an odd fact of human nature that a lot of people seem attracted to this behavior. Beats the heck out of me why.
