LLYC analyzes the new political map of Buenos Aires following the May 18 legislative elections

On Sunday, May 18, the Autonomous City of Buenos Aires renewed half of the seats in its Legislature in an electoral process marked by a highly fragmented landscape, following the breakdown of most political-party alliances previously active in the city.

At LLYC, the global Marketing and Corporate Affairs firm, a report was developed to analyze the main election results, the context in which the vote took place, and its political implications both locally and nationally.

The Buenos Aires election sets a precedent in this year’s electoral calendar, boosting La Libertad Avanza ahead of upcoming electoral agreement discussions with other actors. The victory of the president’s party in what has long been a PRO stronghold cements it as the most representative force for those opposing Kirchnerist Peronism. For the city government, the new configuration of the local Legislature presents a governability challenge, which, in the words of the Mayor, will require a “greater exercise in dialogue.”

The report also addresses the impact of institutional decisions such as the suspension of the PASO primaries, the separation of election dates, and the incorporation of technology, as well as the performance of key candidates and how political forces are positioning themselves for future electoral processes.

The publication includes charts, comparative data, and expert analysis, with the goal of providing tools to help interpret a shifting political landscape in both Buenos Aires and the country overall.

In the words of María Eugenia Vargas, General Manager of LLYC Argentina: “In this transitional context, the report serves as a tool to offer insights into how power is being reshaped in the City. Through contextual analysis, tracking candidacies, and assessing the institutional impact of the results, we aim to contribute to a more informed public conversation on the future of Buenos Aires.”

Meanwhile, Alejandro Stivaktas, LLYC’s Public Affairs Manager, emphasized: “The report on the electoral process in Buenos Aires City provides an in-depth analysis of the context in which the election unfolded, the performance of each political force, the distribution of seats, and key takeaways for interpreting the new local and national political map. It covers the PRO’s ability to regroup for 2027, the impact of the results on the national government, the current positioning of Peronism, and potential projections for new alliances. All these elements are examined to better understand the political scenario that is emerging post-election.”
