I believe every outlet has to have at least one Why Trump Won piece and this is one of the better examples. Certainly looks from here as though the Democrats lost at least as hard as Trump won, but then it's hard right? You lived your whole life in a certain environment and it has always worked out fine for you, why would you expect that to change? Seems like a lot of Washington had no idea how thin the ice they have been skating on for decades had grown. Will be interesting to see what comes of that.
Something that seems to be is missing from a lot of analysis is that nobody outside cities votes Democrat. Maybe if they acted like they were remotely interested in people outside major conurbations, the map wouldn't be a huge red expanse between a pair of thin blue brackets. But then this time around they didn't really seem that interested in anyone really.
