Election Day Results: Shift to Opposition
Bolivia’s August 17, 2025 general election dealt a historic blow to the Movement for Socialism (MAS) after almost 20 years in power. Results revealed centrist and right-wing parties were in the lead, while the MAS nominee lagged far behind. Former President and MAS leader Evo Morales had been barred from running, and outgoing President and MAS leader Luis Arce declined to stand, leaving the party fractured. This marked the first time in nearly two decades that MAS lost, at a moment when Bolivia was suffering “its worst crisis in a generation,” marked by inflation and fuel shortages.
In a stunning defeat, MAS lost its long-held supermajority. All 21 of its Senate seats and all but 2 of 75 lower-house seats went to opposition parties. Centrist and right-wing blocs now hold roughly three-quarters of the 166-seat Congress. Outgoing President Arce quickly accepted the results, stating that “democracy has triumphed.” Morales, from exile, denounced his exclusion and had urged supporters to boycott the election instead
For the first time since 2002, an incoming government will not face obstruction from a MAS-controlled Congress. In effect, the election ended a two-decade era of leftist rule; MAS had won every previous national vote since 2005 and maintained wide legislative majorities until now. The opposition Christian Democrats, Liberals and right-wing parties will soon have the power to pass legislation on their own.
MAS Party: Rise and Political Dominance
Movimiento al Socialismo (MAS) is a left-wing party founded in 1997 from coca-growers’ and Indigenous unions. It first rose to national power with Evo Morales’s presidency. In 2005 Morales won Bolivia’s presidential election by a wide margin. His government immediately nationalized the gas and oil industry and allocated revenues into social programs, driving sustained growth and cutting extreme poverty roughly in half. Over the next decade, the economy continued growing under MAS rule.
MAS won every election for the rest of the Morales era. In 2009 and 2014 Morales was re-elected with first-round majorities. By 2014 the party “gained the majority of seats in both houses of Congress,” according to Britannica. Morales’s administration rewrote the constitution to expand Indigenous rights and executive powers, solidifying power yet maintaining widespread support, especially from Bolivia’s indigenous groups, which comprise around half of the nation’s total population.
Decline of MAS’s Base and Fall from Favor
By 2025, many of MAS’s traditional supporters were disillusioned. Long-time backers in the highland Aymara and Quechua regions felt the party had failed to deliver on its promises. In interviews, Indigenous activists said MAS’s focus on identity and symbolism had not improved living standards: “Indigenous identity was paraded in speeches… but it never translated into better healthcare, education or justice,” one protester said.
Younger voters, many of whom were born under MAS rule, voiced even stronger frustrations. They cited rising inflation - over 23% by mid-2025 - chronic fuel and currency shortages, and poor public services as evidence that MAS had underperformed. As 30-year-old administrative worker Paolo Monroy said, “The left has already shown that it does not work for Bolivia. We need radical change.” In fact, the official MAS candidate polled barely 3%, a signal that MAS had lost its appeal for many voters.
Implications and Significance of MAS’s Defeat
Bolivia’s election results mark a paradigm shift. “These elections really spelled the end of the MAS,” said an expert in Bolivian politics at Texas A&M University. Bolivian political analyst Veronica Rocha even called it the end “for an entire model of government.” Indeed, for the first time in 23 years, a Bolivian government will govern without facing a hostile MAS legislature.
Financial markets responded: the yield on Bolivia’s 2030 bond fell sharply after the first-round vote, as investors predict Bolivia’s new government will pursue orthodox policies. Leading opposition figures did promise a change of course: ex-president Jorge “Tuto” Quiroga spoke of “radical change,” including spending cuts and reversing subsidies, while centrist Paz talked about a “great transformation” of Bolivia’s economic model. Analysis from Reuters even suggested that Bolivia’s rightward turn “may foreshadow a death knell” for other nations led by leftist governments, with elections coming up in Chile and Colombia in early 2026.
Whatever the outcome of the October runoff, MAS will no longer drive Bolivia’s course. The party just cleared the 3% threshold needed to remain registered, but its power has evaporated. A new coalition of centrist and conservative leaders will soon take office, who will need to take actions to rescue Bolivia’s economy, restructure its alliances, and lead it towards a new era.
