Not exactly political correctness but it is contempt. I think the contempt for Trump and his supporters by the other side explains a lot of both the result and the incorrect predictions in advance of the election. A lot of the country literally could not imagine a Trump win.

The contempt stems from political correctness. Political correctness isn't some superficial outrage, it's the genuine belief that people who don't hold progressive beliefs are bad people who need to be punished. Trump can't convince progressives that his views are reasonable, but he can show that these views can't be repressed anymore.
