Sunday, May 18, to renew half of the City Legislature in Buenos Aires. This critical mid-term vote will decide 30 out of the 60 seats, signaling the political direction of the city under the new libertarian wave sweeping the nation.

Voting is being carried out using the Single Electronic Ballot system, designed to increase transparency and streamline the process. Early turnout reports indicate strong civic engagement, with participation surpassing 20% by 1 p.m.

The list of candidates includes high-profile figures such as Manuel Adorni from La Libertad Avanza, Leandro Santoro representing Es Ahora Buenos Aires, Silvia Lospennato from Buenos Aires Primero (PRO), and former mayor Horacio Rodríguez Larreta under the Volvamos Buenos Aires banner. Libertarian economist Ramiro Marra is also running with UCeDé, along with leftist candidates like Vanina Biasi and Lucille Levy from Evolución.

Polls remain open until 6 p.m., and preliminary results are expected by 7:30 p.m., once at least 25% of polling stations and 33% of each commune’s votes are counted. Early projections will offer insight into the momentum of President Javier Milei’s political coalition in the capital, a stronghold critical to implementing broader reforms.

This election is more than a local affair—it is a referendum on Argentina’s libertarian experiment and a test of support for Milei’s sweeping economic and institutional transformation.
