| Source: Corte Nacional Electoral (a)Bolivia's electoral system used List-PR on a single ballot for presidential and legislative elections. The 1995 Constitution modified this system to a mixed member plurality system. Ballots since 1997 have two parts: one for the plurinominal lists and another for the uninominal single-member distric candidates. Figures for subsequent elections reflect votes for the plurinominal list. |
