Peggy Noonan today quotes a cabbie shouting from his cab that he supports Trump because he is “neither left not right”. But wait, didn’t Clinton finish this job off in the 90s with his fabled “triangulation”? Yes, Clinton did an excellent job in his own way of difference-splitting for political gain. But in retrospect his accomplishment seems to be more that he created a new elite consensus. Triangulation can be extended to include another corner, creating a rectangle, with Trumpism another form of triangulation in a populist direction.
