Given that Hitler had repeatedly vowed to use the democratic process in order to destroy democracy, why did the people committed to democracy let him do it? Many historians have jousted with this question, but perhaps the most piercing account remains an early one, written less than a decade after the war by the émigré German scholar Lewis Edinger, who had known the leaders of the Social Democrats well and consulted them directly— the ones who had survived, that is— for his study. His conclusion was that they simply "trusted that constitutional processes and the return of reason and fair play would assure the survival of the Weimar Republic and its chief supporters." The Social Democratic leadership had become a gerontocracy, out of touch with the generational changes beneath them. The top Social Democratic leaders were, on average, two decades older than their Nazi counterparts.
