Is the key to Donald Trump's success just old-fashioned racism? He surely stokes race hatred among his followers and even more-or-less openly panders to anti-Semitism. Yet he also seems to feed on economic desperation. He has won running against trade, his support tracks inversely with educational attainment, and he's posted his biggest margins in some of the most desperate counties in America; surely economic anxiety has something to do with his rise. This has led to various attempts to untangle race from economic factors in predicting Trump's support.
