Trump Wins Every Fourth Election

After Donald Trump got elected, there was this backlash against Nate Silver that he is no longer able to predict elections. I found it amazing because I was following the exit polls and the polling on his website for a while. He certainly gave a much higher probability of Trump winning that most did for sure. But when we get a result that is not something that we were, you know, necessarily expecting like Trump winning an election, the question necessarily has to be, well, did we just get unlucky?
