I keep coming back to the fact that the most discouraging thing about the Trump debacle is that the choice between Hillary and Trump was the most obvious choice in the entire history of elections going back to ancient Greece, and yet 90+% of those on the Right and a not insignificant number on the Left couldn't manage to get it right.  No matter what happens in the future, it is clear nearly half of voters can't be trusted to manage the political version of adding 1 plus 1 without getting 47 as the answer.
