Political mobilization is increasing across various Argentine provinces as different factions prepare for future elections.

In Santa Cruz and San Luis, Peronist leaders are organizing to rebuild the Justicialist Party (PJ). In Santa Cruz, former governor Daniel Peralta has called for unity to reclaim provincial power in 2027, while in San Luis, former governor Alberto Rodríguez Saá has led gatherings of militants seeking his return to the governorship.

Simultaneously, in Buenos Aires, leaders from La Libertad Avanza and the PRO, including Diego Santilli and Sebastián Pareja, are emphasizing the need for coalition unity. Their strategy focuses on maintaining cohesion across 135 municipalities to prevent opposition splits from affecting election outcomes.
