Argentina midterms: Milei’s LLA wins national vote, strengthens grip — but still short of a majority

Argentina voted on Sunday, October 26, 2025, in legislative midterms that served as a referendum on President Javier Milei’s shock-therapy economic program. With most ballots counted, La Libertad Avanza (LLA) topped the national deputies vote at ~41%, a clear first place that expands Milei’s congressional footprint while leaving him short of outright control. Turnout hovered around ~68%, lower than historical norms.

Preliminary tallies indicate LLA is set to capture about 64 of the 127 lower-house seats at stake and at least a dozen of the 24 Senate contests this cycle—numbers that improve the president’s bargaining power but still require alliances to pass sweeping reforms. Party strategists cast the result as a mandate to press ahead; opposition leaders vowed to resist the most controversial measures. (Seat counts remain provisional as the official canvass continues.).

The vote unfolded under new rules: it was the first national election using the unified paper ballot (Boleta Única de Papel) and the first without the PASO primaries, which were suspended for 2025—changes that reshaped campaign strategies and voter behavior.

Early provincial maps show LLA performing strongly across major districts—including Buenos Aires Province and large heartland provinces—signaling a broader electoral coalition than in past cycles. Analysts note that while the government gains momentum, it will still need centrist partners to advance its agenda in a fragmented Congress.

The Interior Ministry will finalize the count and seat allocations in the coming days. Market and policy reaction will hinge on whether post-election talks deliver durable legislative alliances to translate the result into laws.
