Yes, this was one of many studies correlating racial attitudes with support for Trump. One of the more telling findings of the study you cite is that economically-struggling voters tended to vote for Clinton.

The data simply doesn't bear out the narrative that support for Trump was driven by "neo-liberalism," which MSW continues to insist has "collapsed." (It hasn't.) Rather it was driven by cultural resentments and uncritical submission to a campaign of demonization against Hillary Clinton that had been in process for twenty-five years.
