How do legislators respond to coethnic and cominority constituents? We conduct an audit study of all state legislators to explore white legislators’ responsiveness to different minority groups and minority group legislators’ responsiveness to each other. Black and Latino Americans currently make up about one-third of the overall U.S. population and an even larger share of some state populations. In light of this growing diversification of the American electorate, legislators may have incentives to appeal to a broad racial constituency. In our experiment, state legislators are randomly assigned to receive an email from a white, Black, or Latino constituent. Our findings suggest a lack of legislators’ discrimination, on average, against Black relative to white constituents. Instead, we find that all legislators, on average, respond more to both white and Black constituents relative to Latinos. The evidence suggests that Black legislators do not exhibit coethnic solidarity toward their Black constituents or cominority solidarity toward their Latino constituents; however, Latinos do exhibit coethnic and cominority solidarity (though there are too few Latino legislators to definitively establish this claim). We also estimate effects among white legislators by party and racial composition of districts in order to provide suggestive evidence for white legislators’ intrinsic vs. strategic motivations.
