Thomas Reese, thirty years ago I was lucky enough to attend a panel discussion of elderly German Jews who lived through the First World War, the Weimar Republic, and the early years of the Third Reich.  When asked if they were afraid of the Nazis before they came to power, their unanimous answer was, "No, because Adolph Hitler was just a clown who could never get into power, and, even if he did, he wouldn't last a month."

People of left, right, and center have all underestimated Trump.  He certainly isn't as crafty or disciplined as Hitler, but we underestimate him and the damage he can do at our peril.
