Four years ago, in the final weeks of the election, I was too quick to write Donald Trump’s political obituary. I was sure, like many others (including Trump himself), that he would lose. My mistakes included underestimating people’s general disdain for Hillary Clinton, and believing that the national sentiment toward Trump (as reflected in the national polls) would be indicative of what we would see in key swing states. I was wrong, and I was immediately upfront about that.
