Buenos Aires City politics is again moving around a hypothesis that could reorganize both PRO and La Libertad Avanza: the possibility of reviving an alliance in the capital. Jorge Macri left that door open as he prepares his path toward another term and seeks to prevent competition among nearby political forces from benefiting Peronism.
The mayor argued that an understanding with the libertarians should not be ruled out and placed the discussion in contrast with Kirchnerism and Justicialism. His message seeks to present a potential coalition not merely as electoral engineering, but as a way to prevent a political return he considers harmful for the City.
The strategy also has an internal dimension. Macri is trying to sustain the leadership of the Buenos Aires City PRO while pushing a negotiation that could lead to a common candidacy or to a mechanism of competition within a broader front. In that scenario, the capital becomes a testing ground for coexistence between local Macrism and the libertarian space.
Recent legislative cooperation provides a concrete precedent. The city government and La Libertad Avanza shared votes on initiatives such as changes to the law against illegal car watchers, the 2026 budget expansion and support for economic incentive tools such as the City's RIGI and RIMI. That exchange shows that political affinity has already had a parliamentary expression.
On the libertarian side, however, definitions remain open. Karina Milei met with Buenos Aires City lawmakers, technical teams and the local bloc leadership to advance territorial organization and a platform of their own. Among the issues raised by that space are waste management, circulation problems caused by railway barriers and the pending development of the southern part of the capital.
The final shape of the puzzle will depend on names, method and timing. While PRO seeks to preserve control of the City, La Libertad Avanza is evaluating how to capitalize on its growth without becoming subordinated to another structure. The Buenos Aires City negotiation therefore anticipates more than a local election: it also tests how far convergence can go between two political families that share opponents but compete for the same electorate.
