Replication Data for: Assessing Robustness of Findings About Racial Redistricting’s Effect on Southern House Delegations

We assess the robustness of Shotts’s (2003a) finding that racial redistricting increases the number of Southern representatives to the left of the U.S. House median. Our results, which are based on Monte Carlo simulations and an alternative measure of representatives’ preferences, are broadly consistent with Simons and Mallinson’s (2015) null findings. The data do not support the claim that racial redistricting promotes liberal policy outcomes; nor do they support the claim that it promotes conservative policy outcomes. At a methodological level, we suggest techniques that researchers can use to assess how robust their findings are to noise in variables based on estimated values like DW-Nominate scores.
