If only Brooks turns out to be right.  But there's a very good chance that he's underestimating Trump, the same way those who thought they could control Hitler underestimated him.  It is already clear that Trump is the first American president at least since John Quincy Adams to govern outside the two-party system.  Nominally, he's a Republican.  But he really has no loyalty to anything but the Trump brand.  Never in his career has he accepted sustainable collaboration.  He's always had to be the one in control.  He doesn't even listen to advice, except from advisers hand-picked to tell him what he wants to hear.  This might make him inept and bumbling, except for one thing: Trump, like Hitler, has genius at reaching out directly to his fact-challenged and emotionally-driven base.  He will make them steadily more militant.  The Resistance of course will grow, and will also become more militant. This is a formula for more than constituional crisis.  It's a formula for street conflict.
