As Michael Barone says in his write-up, the creator of the map (below) seems to have gotten this right, based on the collateral data available about the vote. Obviously, we don’t record the identity or race of each voter, so it requires estimation based on exit polls and local demographics to come up with the figures for this.
But intuitively, the presentation is what you’d expect, especially given that “whites voted 58 to 37 percent for Trump over Clinton.”
That said, it’s still arresting to see it depicted. Barone offers insightful analysis about each Hillary enclave; e.g., here:
Central cities with heavy gentrification. New York, Washington, Chicago, San Francisco, Portland, Seattle. But Philadelphia and Pittsburgh too, and Richmond, Va., both Minneapolis and St. Paul, and even Milwaukee. New Orleans and St. Louis have limited gentrification but arguably also fall into this category.
University towns. Ithaca, N.Y.; Charlottesville, Va.; Durham and Chapel Hill, N.C.; Athens, Ga., and Athens, Ohio; Bloomington, Ind.; Ann Arbor, Kalamazoo, and Marquette, Mich.; Champaign and Urbana, Ill.; Eau Claire, Wisc.; Iowa City and Ames, Iowa; Yankton S.D.; Missoula, Mont.; Lawrence, Kan.; Eugene, Ore.; and Boulder Colo.
He doesn’t linger on it, but one thing that really jumps out at me is how clearly we can see the collapse of the old Midwest’s “Blue Wall.” Hillary didn’t lose everybody in Ohio, Michigan, Wisconsin — but she sure did lose a lot of white voters.
