The Botswana Democratic Party (BDP) has maintained a super-majority in the National Assembly for over forty years despite increasingly competitive elections. Several factors contribute to the BDP's continued legislative dominance, including features of the electoral system, fragmentation of the party system, and obstacles to strategic voting behaviour. Factional competition has played a particularly important role. Botswana's political institutions encourage factional competition, and factionalism interacts with the electoral system to hinder consolidation of the party system. Botswana's experience underlines the importance of internal party dynamics and their interaction with features of the electoral and party system in enabling the persistence of legislative dominance in competitive electoral systems.
