A look at the polls in Austria and Germany cannot fail to provoke alarm for anyone familiar with the 1930s, and especially for those who witnessed that decade, as I did as a child. I can still recall listening to Hitler’s speeches, not understanding the words but finding the tone and audience reaction chilling enough. The first article that I remember writing was in February 1939, after the fall of Barcelona, on the seemingly inexorable spread of the fascist plague. And by a strange coincidence, it was in Barcelona that my wife and I watched the 2016 election returns.
