Where did white voters back Hillary Clinton?

Where did whites vote for Hillary Clinton over Donald Trump? Not all that many places, if you take a look at this map from the Amazing Maps twitter account (h/t Patrick Ruffini’s Twitter feed).

When you look more closely, however, you will see that this geographically dispersed group of counties includes lots of heavily populated places, from New York City through Chicago’s Cook County to Los Angeles County. According to the exit poll, whites voted 58 to 37 percent for Trump over Clinton; there’s no indication who drew the map, or on the basis of what data, but from my own examination of the election returns he or she seems to have gotten the results pretty close to right.
