The biggest tragedy of all is that people often tend to make up their minds based on emotions rather than facts, and hear what they want to hear. Trump's base has shrunken only slightly, but all we have to do in order to set things right is to stop ignoring the problems that are making people "mad as Hell." This is not as difficult as it may appear. There are a lot of people who stayed home last time because they didn't like either candidate and are now as energized as a space probe. It will become increasingly difficult for special interest groups to persuade them either not to vote at all, or to vote against their own best interests.
Hitler also taught that a big lie would be believed easier than a little one if it were repeated often enough, so he w restricted his big lies to only these two alternative facts. Nevertheless, the most important reason that Trump does not pose as much of a danger as Hitler did is obvious. Hitler was a much better speaker! He even made use of lighting, symbols, and audience involvement to drive home his points. Here, with English subtitles, is one of his classic speeches. Judge for yourself.
