The PRO bloc in the Chamber of Deputies has suffered a significant drain in recent weeks, going from 24 members before the October 2025 legislative elections to only 12 currently. This reduction is mainly due to the migration of legislators aligned with Patricia Bullrich to La Libertad Avanza (LLA), the space led by Javier Milei, after the official victory in the elections. Others have opted for independent or provincial blocs, weakening Mauricio Macri’s position and reflecting internal tensions due to strategic disagreements and ideological affinities with the libertarian government. Inspired by the “libertarian plan” that already in May 2025 began to “pluck” Macrism, this recent exodus consolidates LLA as a dominant force in Congress, reaching up to 95 deputies.
Below is the list of the twelve deputies who left the PRO bloc in recent weeks (from the end of October to the beginning of December 2025), with details about their career, reasons and destination, correcting the provinces of origin based on verified information:
- Damian Arabia: Former vice president of the PRO, expelled by Macri in August 2025 for alleged absences, but really because of his closeness to the libertarians. He broke with the bloc on October 31 to join the LLA, arguing the need to align with Milei’s reforms. Origin: Autonomous City of Buenos Aires (CABA).
- Sabrina Ajmechet: Buenos Aires deputy, historian and ally of Bullrich. He left the PRO on October 31 to join LLA, prioritizing “change” and tightening security. Origin: Autonomous City of Buenos Aires (CABA).
- Laura Rodríguez Machado: Accountant from Córdoba, re-elected in 2021 and 2025, leader of the agricultural wing in bullrichism. She left Macri’s party on October 31 to join LLA, upset by Macri’s disinterest in key campaigns. Origin: Córdoba.
- Silvana Giudici: Former Buenos Aires official under Macri, communications specialist. It moved to LLA on October 31, aligned with Bullrich on antiterrorism and deregulation issues. Origin: Autonomous City of Buenos Aires (CABA).
- Patricia Vazquez: Buenos Aires deputy, with experience in education and security. He broke with PRO on October 31 to join LLA, emphasizing ideological convictions shared with Milei. Origin: Province of Buenos Aires.
- María Luisa González Estevarena: Elected in 2025 by CABA, with a focus on urban planning and transportation. He joined LLA directly on December 10, leaving the PRO out of loyalty to Bullrich. Origin: Autonomous City of Buenos Aires (CABA), although elected as a national representative for the Province of Buenos Aires in some contexts.
- Carlos Almena: Elected in 2025, businessman with a low profile. He joined LLA since December 10, criticizing Macri’s stagnant leadership and betting on libertarian renewal. Origin: San Luis (Villa de Merlo).
- Aníbal Tortoriello: Businessman from Rio Negro, he competed in the 2025 lists. He left PRO to join LLA on December 10, avoiding Macri’s “unrelated negotiations” and aligning himself with the ruling party. Origin: Río Negro.
- Alejandro Bongiovanni: Representative for Santa Fe, agricultural producer. He confirmed his move to LLA at the end of November out of affinity with Milei’s economic reforms, strengthening the ruling bloc to 94 members. Origin: Santa Fe.
- Veronica Razzini: Legislator from Santa Fe, she previously distanced herself from the PRO. He formalized his entry into LLA in November, after a brief stint in an intermediate bloc, seeking to represent the interior with liberal policies. Origin: Santa Fe.
- Belen Avico: Córdoba deputy from Río Cuarto. He went to LLA in November, leaving the PRO without representation in Córdoba and criticizing the lack of renewal in Macrism. Origin: Córdoba.
- Jose Nunez: Santa Fe legislator. He left PRO at the end of November to join the Provincias Unidas bloc, prioritizing provincial initiatives and selective support for the national government. Origin: Santa Fe.
This massive defection, which includes both current and elected deputies, marks a turning point for the PRO, reducing its influence and positioning LLA close to its own quorum in Deputies. Macri has tried to stop the flight with personal appeals, but internal divisions persist, with the focus now on preserving party identity for 2027.
