President Javier Milei’s La Libertad Avanza (LLA) party stunned Argentina with a commanding 40.84% of the vote in the October 26, 2025, midterm elections, securing a historic mandate to advance his radical reform agenda. Speaking to ecstatic supporters in Buenos Aires, the 55-year-old leader called the results a “turning point,” vowing to build “the most reformist Congress in Argentina’s history.” The LLA tripled its presence, capturing 101 seats in the Chamber of Deputies (up from 37) and 20 in the Senate (up from six), while the Peronist movement, a historic powerhouse, trailed with 31.64%. The victory signals strong support for Milei’s vision of a leaner, market-driven Argentina despite economic turbulence.

The elections, filling half the lower house and one-third of the Senate, were a critical test of Milei’s leadership since taking office in December 2023. His aggressive reforms—slashing public sector jobs, halting public works, and cutting health, education, and pension spending—have slowed inflation by two-thirds but deepened poverty and slowed growth. A recent peso crisis forced Milei to secure a $40 billion U.S. bailout, backed by President Donald Trump, who tied aid to electoral success. The LLA’s surprising gains in the Peronist stronghold of Buenos Aires province highlight Milei’s growing appeal, even amid controversies involving corruption scandals in his inner circle.

At the LLA’s victory rally, supporters celebrated with chants, hugs, and tears. “This feels like winning the World Cup!” said Facundo Campos, a 38-year-old marketing consultant, amazed by the margin of victory. Maria Jesus Galan, a 45-year-old health official, praised Milei’s potential despite “some missteps.” Voters like Adriana Cotoneo, a 69-year-old pensioner, backed LLA to oust the Peronists, led by the embattled Cristina Kirchner, who is under house arrest for corruption. However, a record-low 67.9% turnout reflects widespread frustration with Argentina’s political class.

Economic fears dominated the election’s backdrop, with investors dumping the peso over concerns about stability. U.S. Treasury interventions propped up the currency, but rumors of a post-election devaluation persisted. Economy Minister Luis Caputo firmly rejected such speculation, saying, “Our economic program stays on track.” With a strengthened Congress, Milei is poised to intensify deregulation and state-shrinking efforts, aiming to revive Argentina’s economy while facing criticism for the social costs of his policies. Supporters see a bold new era, but challenges remain in balancing reform with public needs.

The LLA’s triumph marks a pivotal moment for Milei’s presidency, empowering him to reshape Argentina’s future. His expanded congressional power offers a clear path for his ambitious agenda, but economic fragility and public discontent loom large. As Argentina navigates this transformative phase, global eyes are on Milei to deliver on his promise of a “great Argentina.” The midterm results signal a shift in the nation’s political tide, but whether Milei can sustain this momentum amid mounting pressures will define his legacy.
