Whose party won a stronger-than-expected victory in that vote?

President Javier Milei's party, La Libertad Avanza, won a stronger-than-expected victory in Argentina's October 2025 midterm elections, taking about 41 percent of the national vote compared to the Peronist coalition's 32 percent. The result was closely watched internationally because it was widely seen as a referendum on Milei's aggressive market-oriented economic reforms, and a strong showing gave him a better chance of pushing further changes through Congress.

The Peronist opposition coalition did compete and finished second, not first, and no newly formed centrist party emerged as the actual winner, the vote came down to the established contest between Milei's libertarian movement and the traditional Peronist bloc.

The win came despite record-low turnout in a country where voting is technically compulsory, suggesting that even with reduced participation, the electorate that did turn out gave Milei's economic agenda a meaningfully stronger mandate than expected.
