Jorge Macri tries to close an alliance between PRO and La Libertad Avanza for the 2027 Buenos Aires election, but the understanding is still not defined. The Head of Government believes that an agreement could clear his path to reelection and prevent a competitive libertarian candidacy from splitting the officialist electorate. On Karina Milei's side there is less rejection than a year ago, although not a final decision yet.
The position of Jorge Macri changed after the Port City defeat in May 2025. Later, he accepted an alliance for the national election in October, in which PRO received three seats, and since then he has sought to transfer that cooperation to the district. Among the concessions he would be willing to discuss is the vice-leadership for a leader linked to Karina Milei, with Pilar Ramírez mentioned as a possibility.
La Libertad Avanza maintains incentives to delay a decision. Its legislators assessed the need to put forward their own candidacy, even if just to improve negotiations, and the space does not currently have a settled option after Manuel Adorni's exit from the Buenos Aires scene. Patricia Bullrich, Diego Santilli, or some minister appear as possible alternatives, not as confirmed candidacies.
The approach already has an expression in the Legislature. The PRO accompanied local versions of regulations promoted at the national level, among them the so-called Ley Hojarasca, while the libertarians stopped blocking initiatives from the Buenos Aires Executive as frequently as before. That coordination reduces the level of confrontation, but does not resolve the distribution of candidacies or the future leadership of a potential coalition.
Mauricio Macri adds a third interest to the negotiation. The former president promotes a broad primary and intends for Horacio Rodríguez Larreta to be able to compete within the same framework, although the former head of Government stated that he would not participate if LLA is part of the agreement. Mauricio Macri also does not seem convinced to give a portion of the ticket to the libertarians and keeps as a pressure tool the possibility of competing again in the City.
The discussion is thus crossed by three different calculations: Jorge Macri wants to protect his reelection, Karina Milei must decide between agreeing or disputing the main historical stronghold of PRO, and Mauricio Macri seeks to maintain influence over the electoral architecture. Legislative cooperation offers a starting point, but there is still no formula, selection mechanism, or agreed list of candidates. The next move will depend on whether LLA favors an understanding or installs its own figure to negotiate from a stronger position.
