Dominant party systems are defined by a lack of party alternation at the national level; however, dominant party systems do not inherently preclude electoral competition at the macro level, the micro level, or both. Nonetheless, little systematic work has documented the competitiveness of elections under a dominant party system. This article describes the nature of competition under one of sub-Saharan Africa's most enduring dominant party systems, Botswana. By examining electoral outcomes at the constituency level, this article demonstrates that elections in Botswana produce significant levels of competition, especially when compared to other sub-Saharan countries. Furthermore, electoral competitiveness appears unrelated to the party system at large: namely, competitiveness is no less or greater under dominant party systems than under multiparty systems.
