From the essay:
voters in their study who supported Trump generally had a higher mean household income ($81,898) than those who did not ($77,046). Those who approved of Trump were “less likely to be unemployed and less likely to be employed part-time” than those who did not. They also tended to be from areas that were very white: “The racial and ethnic isolation of whites at the zip code level is one of the strongest predictors of Trump support.”
Maybe your experience is different from mine, but I would be shocked to hear racist crap in that elevated economic level. There is so much hand-wringing over the Democratic Party's neglect of the "white working class" who were drawn to Trump's populism--these numbers indicate that the problem is much bigger than that. We need to attract racists from all economic walks of life.
I hope I don't really need this, but 
Or we could get to work on combating institutionalized racism and put a few cops in jail for starters.
