Unpacking Representation in State Immigration Policy: Latino Composition, White Racial Threat, and Legislator Partisanship

Abstract

AbstractMost research studying minority representation concludes that minorities enjoy better representation when they constitute a larger share of a constituency, but only through the partisanship and race/ethnicity of the representative. Other research finds that minorities receive worse representation when they constitute a larger share of a constituency. We argue that minority composition will have an independent effect on representation, but that this effect will differ depending on the representative's partisanship. We apply our theory to Latino composition and state legislative voting on immigration policy and find that Latino composition has no effect on voting among Democratic legislators, who are less likely to vote in a restrictive direction on immigration than Republicans regardless of the Latino composition in their district. However, Republicans are more likely to vote to restrict immigration as Latinos comprise a larger share of their district. Our findings suggest that scholars should consider the moderating effect of legislator partisanship when examining minority composition and representation.
