Lexicographic Preferences in Candidate Choice. How Party Affiliation Dominates Gender and Race

Abstract

Abstract Understanding which political candidates are elected for office is fundamental to democracy and political science. Whereas there is much agreement that party affiliation is one of the most important candidate characteristics to voters, evidence regarding the gender and race of the candidate is mixed. We suggest voters have lexicographic preferences, meaning they rank their preferences and focus primarily on the candidate's party affiliation. Second-order preferences such as gender and race are mostly necessary when there is a tie in first-order preferences when voters choose between two same-party candidates or have no party information. We show how conjoint experiments can be used to test for lexicographic preferences and use data from a US-representative sample and a pre-registered replication to confirm that in the United States, gender and race are second-order preferences. Lexicographic preferences provide a theoretical lens explaining some of the mixed results of gender and race in the candidate literature.
