Local Electoral Institutions and the Dynamic Motivations of Ethnic Party Candidate Nominations in South Africa

Abstract

How do parties historically dominated by one group diversify their representatives? I argue that ethnic parties adjust their strategies according to the institutional rules in place and the demographics of relevant constituencies. I study South Africa, which has a Mixed-Member Proportional electoral system, where parties nominate Single Member District and Proportional Representation candidates. Using original data on the racial, ethnic, and career background of over 10,000 local candidates nominated by the historically white Democratic Alliance party, I find that the party engages in vote-based inclusion by nominating black candidates to predominantly black districts. And while the DA symbolically includes non-whites on its PR lists, white candidates dominate electable list positions. These findings provide a demonstration at the micro-level of why ethnic parties struggle to meaningfully diversify.
