Were Trump voters motivated by racism or by economic anxiety? This was a running debate in the 2016 campaign that devolved into a kind of running gag. Prestigious newspapers ran long, soulful profiles of down-on-their-luck Trump-supporters in Appalachia or the rural Midwest. Then the liberal wonkosphere would reply with clips of Trump supporters saying heinously racist things at a rally, as well as a little data showing they object to more non-white immigration. My feeling has been that Trump voters were motivated by all the above.
