The Big Tent Effect

Abstract

In this study, we assess whether Blacks and/or Latinos are more likely to identify with political parties that nominate a U.S. House candidate who shares their race/ethnicity using the 2010 Cooperative Congressional Election Study (CCES). Our results indicate that Blacks are more likely to identify with both the Democratic and Republican Party when they nominate successful Black candidates for the House of Representatives. To assess the temporal order of the relationship, we examine the differences in Black Democratic partisanship before and after Obama's election to the White House and changes in Republican partisanship among Blacks in districts before and after the nomination of a successful Black Republican candidate. In combination, we find that both political parties can make gains in the Black community through the nomination of co-racial candidates. While descriptive candidates consistently influence Black partisanship, we find that Latino partisanship is not significantly affected by the presence of co-ethnic candidates.
