Racial Bias and U.S. Presidential Candidate Preference

Abstract

Much research has suggested that Republican candidates in U.S. presidential elections benefit from voter bias against non-White groups. The present study supplements this research by including in the analysis bias against Whites. Estimates from the American National Election Studies 2020 Time Series Study indicated that a nontrivial percentage of the U.S. population has a bias that disfavors Whites, with this bias more prevalent among Democrats than Republicans. Further analyses estimated the extent to which the type of voter racial bias that favors Republican presidential candidates offsets the type of voter racial bias that favors Democratic presidential candidates. Estimates for the 2020 U.S. presidential election indicated that the two-party vote share for Donald Trump was higher among voters who rated Whites, Blacks, Hispanics, and Asians/Asian-Americans equal to each other on 0-to-100 feeling thermometers than among the full population of two-party voters, suggesting that Donald Trump was disadvantaged on net by the electorate including racially biased voters. These results call into question research that has used an unrepresentative set of racial attitudes to suggest that, in recent U.S. presidential elections, only Republican candidates have benefitted from racial bias among the electorate.
