Abstract

<p>Beginning with the 1997 election, Bolivia introduced a mixed-member electoral system wherein constituencies vote through two ballots. The first ballot is a fused ticket based on proportional representation, where votes are cast for the president, the vice president, a party list for the senate, and another list constituting half the members of the Chamber of Deputies. In the second ballot, the electorates vote for a candidate in a single-member district (SMD). Since then, five elections have been held under this system; in all of them, clear signs of split ticket voting can be observed, especially from the third election onward. The most common pattern of split ticket voting showed in the case of popular presidential candidates with party lists and one blank vote. In this study, I conducted a multivariable regression analysis on aggregate electoral data and found that for the first two elections, the ticket splitting was driven by personal voting; however, after the rise of Movimiento Al Socialismo in 2005, an additional factor, a decrease in political efficacy, has started affecting constituencies with regard to casting blank votes in an SMD.</p>
