Race, legislative speech, and symbolic representation in Congress

We know little about the extent to which racial minorities are symbolically represented by members of Congress. This stands in contrast to a wealth of research analyzing the extent to which minorities are substantively and descriptively represented. This article provides the most comprehensive analysis of symbolic representation to date. Using data on legislators’ speech from 105,875 newsletters and 620,838 floor speeches, I find that White legislators of both parties are more likely to symbolically represent Blacks, Hispanics, and Asians if those groups are more populous in their constituency. However, these effects only hold cross-sectionally; using a difference-in-differences setup from redistricting shocks, I find that there is little within-legislator variation in speech patterns as their constituencies change. Lastly, I show that, unlike on the symbolic dimension, legislators’ substantive representation is not influenced by group size. I conclude that White legislators are symbolically responsive to their constituents’ identities in their speech patterns.
