Bolivia’s political landscape has undergone one of its most dramatic transformations in nearly two decades. In the August 17 general election, the long-dominant Movement Toward Socialism (MAS) party suffered a decisive defeat, losing its grip on both the presidency and the legislature. The outcome marks a historic turning point in a country that has been shaped by leftist governance since 2005.
The result reverberated far beyond Bolivia’s borders, drawing attention across Latin America, where political shifts often signal broader regional trends. Full regional context can be found in our americas coverage.
collapse of a political powerhouse
Official results certified by Bolivia’s Supreme Electoral Tribunal (TSE) confirmed the scale of the setback. MAS lost all 21 of its seats in the Senate and secured only two seats in the Chamber of Deputies — a stunning reversal for a party that once commanded overwhelming legislative majorities.
The party’s presidential candidate, Eduardo del Castillo, received just 3.2 percent of the national vote — barely above the 3 percent threshold required for a party to retain its legal registration. Analysts describe the outcome as not merely a defeat but a structural collapse of the political machinery that once defined Bolivian governance.
For nearly twenty years, MAS dominated Bolivia’s political narrative under the leadership of former President Evo Morales and later President Luis Arce. The party built its platform on state-led economic policy, nationalization of key industries, and expanded social programs aimed at reducing poverty and inequality. However, shifting economic realities and internal fractures appear to have eroded its once-solid base.
economic strain and internal divisions
Bolivia’s economy has faced mounting pressure over the past year. Inflation has climbed sharply, foreign currency reserves have dwindled, and shortages of fuel and U.S. dollars have disrupted daily life. Long lines at fuel stations and restricted access to imported goods fueled public frustration, particularly in urban centers.
Economic instability often reshapes electoral outcomes, and Bolivia proved no exception. For deeper analysis on how financial turbulence impacts political transitions, see our markets section.
Beyond economic strain, MAS was weakened by internal conflict. Tensions between Evo Morales and President Luis Arce fractured the party’s leadership. Morales, barred from seeking another term following legal and constitutional disputes, launched a “null vote” campaign urging supporters to cast blank or spoiled ballots in protest.
the impact of the null vote campaign
The protest strategy had a measurable effect. Nearly 20 percent of ballots cast were declared invalid — an unusually high figure in Bolivian elections. Political observers believe the campaign siphoned off a critical share of the leftist vote, fragmenting MAS’s traditional support and amplifying opposition momentum.
The null vote effort underscored a deeper power struggle within the movement. Rather than consolidating support behind the official MAS candidate, divisions within the party appeared to accelerate its decline. In effect, internal dissent translated into electoral vulnerability.
who advances to the runoff
With no candidate surpassing the 50 percent threshold required for an outright victory, Bolivia now heads to a runoff election scheduled for October 19.
Senator Rodrigo Paz of the Christian Democratic Party (PDC) finished first with 32.06 percent of the vote, defying pre-election projections. Former President Jorge “Tuto” Quiroga, representing the Libre alliance, secured second place with 26.70 percent.
The rise of Paz, widely viewed as a centrist, alongside Quiroga, a conservative figure with previous executive experience, reflects what analysts describe as voter appetite for political recalibration. Many citizens appear to be signaling a desire for policy moderation and institutional stability following years of ideological polarization.

what this means for bolivia
The October runoff now represents more than a routine electoral procedure; it is effectively a referendum on Bolivia’s political direction. A Paz victory could usher in a centrist administration focused on fiscal stabilization and institutional reform. A Quiroga presidency would likely signal a stronger pivot toward conservative economic policy and closer alignment with market-driven frameworks.
For MAS, the challenge ahead is existential. The party must decide whether to reorganize around new leadership, reconcile internal divisions, or risk long-term marginalization. The near wipeout in the legislature severely limits its immediate influence over national policy.
Bolivia’s electorate has delivered a message that extends beyond partisan preference: economic management, unity of leadership, and institutional trust remain decisive factors in democratic transitions. As the country prepares for the runoff, both domestic observers and international markets will be watching closely to see whether Bolivia’s next chapter brings stability — or further political turbulence.
