The vast majority of Trump voters were not people who had their jobs shipped overseas but just plain voters motivated by racism so they don't care
Perhaps you are right, but do you have any documentation that racism had the most salience for the "vast majority" of Trump voters in making their candidate selection? My intuition is that protectionism was the most juicy bait for Trump. Voters whose standard of living is stagnant or tanking, with higher paying blue collar jobs getting scarcer and scarcer, grabbed on to the "it's due to jobs being shipped overseas due to bad trade deals" line as if it were a life preserver. They hope that's true, and things will get better once we get rid of the bad trade deals.
