Bolivian Legislative Election - Chamber of Senators, 2019

General elections were held in Bolivia on 20 October 2019. Voters elected all 130 members of the Chamber of Deputies and 36 senators and cast ballots for a joint slate of president and vice president. Disputes over the transparency and legitimacy of the elections prompted weeks of widespread protests in Bolivia after incumbent President Evo Morales was declared the winner with 47.08% of the vote; because this was greater than ten-point margin over his nearest competitor, Carlos Mesa, this was enough for Morales to be announced as a winner without a run-off second-round vote.

Following protests, as well as calls for a second-round election from several foreign countries, Morales, who had pledged to respect the OAS audit, agreed on 10 November to hold new elections, at a date to be determined. On the same day, Morales and his vice president, Álvaro García Linera, resigned from office after losing support from the police and military.
