BUENOS AIRES, Argentina — What was once one the bastion of the center-right in Argentina fell on Sunday to the radical libertarian party of President Javier Milei, a dramatic result that could help the leader's chances in crucial midterm elections later this year as voters across the country's capital abandoned the main conservative party.
Milei's top candidate and official spokesperson, Manuel Adorni, swept to victory in the Buenos Aires elections, securing over 30% of the ballots and crushing the center-right party of former President Mauricio Macri in its stronghold.
Milei's La Libertad Avanza party, or LLA, said it racked up twice as many votes Sunday as it did in the last local election, in 2023.
As a brassy Argentine rock anthem blared at the post-election rally, Milei burst onto the stage, bouncing and pumping his arms to whip up the crowd.
''Today is a pivotal day for the ideas of freedom,'' he bellowed, reveling in the cheers of supporters.
The upset marked a bruising defeat for Macri's PRO (Republican Proposal) party, which has governed Buenos Aires uninterrupted for the past 18 years. The PRO candidate, Silvia Lospennato, came in third with 15.9% of the vote.
''The results are not as expected,'' Lospennato acknowledged. ''We have a lot of work ahead of us."
Argentina's left-leaning populist Peronist party, which has governed the country for much of the past two decades, came second, scraping over 27% in a city where they normally fall short, a sign of how the splintered right-wing has benefited the opposition.
