Buenos Aires 2025 Elections: Peronist landslide victory and political consequences

by September 7, 2025

Peronism achieved a resounding and irreversible victory in the Buenos Aires province elections. According to official counts, Fuerza Patria won by a landslide in the first and third electoral districts, which together account for almost 60% of the 14 million voters eligible to vote today. In addition, the party triumphed in the second, fourth, seventh, and eighth districts.

province— four sections elected senators and the other four elected representatives—Fuerza Patria garnered nearly 47% of the vote, a lead of more than 13 points over La Libertad Avanza, which only won in the fifth and sixth sections.
Axel Kicillof emerged as the big winner of the day. His commitment to splitting the election, criticized by sectors of Peronism itself, was validated by the results. The resounding victory not only strengthens his leadership in the country's most populous province but also establishes him as a central figure for the opposition and a possible presidential candidate for 2027.

The celebration in La Plata was immediate: the official bunker resounded with chants and gestures of triumph that underscored the political resonance of the day.
For the Casa Rosada, however, the result presents a complicated scenario. Although the ruling party had moderated its expectations in the days leading up to the election, no one expected such a wide margin in favor of Peronism. In the La Libertad Avanza bunker, demands for explanations began, and the first to be singled out for the electoral fall were prominent figures with high public visibility and responsibilities in the campaign.

Criticism arose over strategic decisions, candidate selections, and the impact of scandals that ultimately undermined credibility. The ruling party is trying to highlight the seats it retained, but internal doubts are growing about who should assume political responsibility and how to redefine the communications direction before October. Section by section, contrasts are evident. In the First, the list headed by Gabriel Katopodis surpassed 47% and was ahead by more than ten points over Diego Valenzuela's list, in a section with nearly 4,800,000 voters; with these figures, Fuerza Patria won the majority of the seats up for grabs.
In the Second, Diego Nanni's ticket won by about six points over Natalia Blanco's, although both parties obtained representation in provincial deputies. In the Third, Verónica Magario achieved more than 53% and left the ruling party list below 30%, consolidating a broad constituency for Peronism.

The Fourth Vote also showed Peronist dominance: Diego Videla's slate surpassed 40%, relegating La Libertad Avanza to second place. Meanwhile, the Fifth Vote won for the ruling party: Guillermo Montenegro prevailed by a narrow margin. The Sixth Vote, for its part, favored La Libertad Avanza in the race for seats.

The Seventh and Eighth elections consolidated Peronism's gains: Fuerza Patria won the contested seats and expanded its legislative presence. In the Eighth, the margin in favor of Peronism was close to six points.

The immediate implications are clear: with this result, Peronism will have greater capacity to advance its agenda in the Buenos Aires Legislature. A stronger provincial bloc will facilitate the passage of laws and the implementation of public policies over the next two years.

For its part, La Libertad Avanza faces the need to review its strategy in the Buenos Aires province. Internal tensions are deepening due to criticism of the candidate selection process and episodes of public visibility that failed to deliver at the polls. Questions are now being raised about responsibilities and tactics to try to reverse or mitigate the electoral impact in the run-up to October.

On the national front, analysts interpret the election as a sign that the relationship with society demands more attention to specific issues: retirees, people with disabilities, and university students emerge as groups whose situation influenced the vote. It is also clear that political communication and territorial presence continue to be decisive in deciding results in the country's largest province.

The political repercussions were immediate. Complaints about the campaign strategy, the selection of candidates, and the lack of local agreements that could balance forces in key districts multiplied in official offices. Several key figures became the focus of internal debate, and clarifications were sought regarding the preparation of lists and communication.

The winning side celebrated the combination of territorial structure and a clear narrative. For the Peronists, the victory validates a roadmap based on presence in the neighborhoods and concrete proposals for employment, health, and education. Initial analyses agree that this closeness was decisive in attracting undecided voters.

Analysts point out that the Buenos Aires elections confirm a rule: territoriality and coherent communication are fundamental. For the national ruling party, the numbers force it to adjust its tactics, review its candidacies, and demonstrate tangible social results before October.
Finally, the province of Buenos Aires once again proved that it defines national narratives. The night left Kicillof with reinforced political capital and the opposition with the urgent task of rebuilding trust; what happens will mark the map toward 2027.
