So many times in the last two years, conservatives have given their cosmopolitan liberal friends a curious look and said something to the effect of, “Sorry, but this is how you got Trump.”

Opportunities for this abound, for the political Left displays an astonishing lack of introspection about how extreme they’ve become and how the 2016 election snuck up on them. “It was just a few thousand people in a handful of states!” they say, brushing off more fundamental reasons for their candidate’s defeat in 30 of the 50 states. People who disagree with them on politics, find their agenda repellent, or merely live traditional lives of work and worship disdained by coastal bien-pensants are treated with smug superiority. They are too low to merit explanation.
