The story began with a modest landing. In the 2021 legislative elections, Milei and Victoria Villarruel entered for CABA with 17% of the votes and embodied the anti-system irruption of the space. When both left their seats in 2023 to assume the Presidency and Vice Presidentship, their places were occupied by Nicolás Emma and Ramiro Marra, the minimum core of a bloc that would only reach a certain muscle in 2023 with 38 legislators, still very dependent on the PRO.
The final leap came in 2025. In the legislative elections of October 26, LLA won in 15 of the 24 districts and added 64 elected deputies, an unprecedented number for a force born without a territorial structure. Added to that were 29 continuators of mandates started before 2025. The ballot designed by Karina Milei and Eduardo “Lule” Menem mixed pure libertarians with macrista and radical figures who sought to recycle themselves under the violet seal. Buenos Aires, Córdoba and Santa Fe contributed most of the flow.
In this group, names with high political or media impact stand out: Diego Santilli as a bridge with bullrichista Macriism; Karen Reichardt as a pop bet in Buenos Aires; Alejandro Fargosi and Patricia Holzman in CABA; Gonzalo Roca as a reference for the interior of Cordoba; Agustín Pellegrini, symbol of generational renewal in Santa Fe; Luis Petri from Mendoza, as an example of the absorption of ex-radicals; Ignacio Noceti in Salta and Maira Frías in Chubut, as key territorial anchors. The strategy, confirmed by the Electoral Justice, combined 70% libertarian profiles with 30% tactical allies.
But the real leap was not made at the polls but later. In November, a wave of 14 post-election adhesions promoted by Patricia Bullrich and endorsed by Karina Milei took the bloc from 83 to 94 deputies. Among the most resonant passes were Sabrina Ajmechet, Silvana Giudici and Verónica Razzini from CABA and Santa Fe; the Cordobans Damián Arabia, Laura Rodríguez Machado and Luis Picat; as well as figures such as Alejandro Bongiovanni, Lorena Petrovich, Mariano Campero and Federico Tournier. All justified their jump in “libertarian convictions” and the need to shield presidential vetoes, which require 86 votes.
The libertarian growth leaves Peronism with 98 seats, but crossed by internal tensions and possible provincial escapes – such as those speculated in Catamarca -, which could further narrow the gap. Milei, thus, ensures a Congress more compatible with its labor, tax and State reforms.
From the symbolic debut of 2021 to the purple dominance that will be seen in the chamber on December 10, LLA starred in the fastest expansion of a political force since the democratic return. The unknown now is not how many there are, but how long the cohesion of such a broad and heterogeneous bloc will last, in an ruling party that has already experienced ruptures, such as that of Marra in 2023. For now, Milei achieved what seemed improbable: going from two deputies to a bloc that is close to a hundred and that fundamentally alters the arithmetic of power.
