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 ro persuade them either not to vote at all, or to vote against their own best interests.
We survived the Civil War and the Great Depression, and we will survive Trump too, regardless of whether or not he is impeached and removed from office. Our days of world leadership, however, have been dealt a severe blow -- although many people overseas will say that this is not such a bad thing, as long as we don't all end up speaking Russian or Chinese.
