Overview

• In Sunday’s legislative renewal, voters will choose 127 national deputies and 24 senators, in line with the Constitution’s staggered schedule.
• Five populous districts—Buenos Aires, CABA, Santa Fe, Córdoba and Mendoza—hold 63.3% of the electorate and will fill 71 of the 127 lower-house seats at stake.
• La Libertad Avanza is seeking a near one‑third bloc in the Chamber of Deputies, a target that analysts say could help sustain presidential vetoes against adverse laws.
• New Senate projections reported by La Nación suggest a smaller libertarian surge than anticipated, with internal tallies now pointing to wins in CABA, Chaco and Entre Ríos and runner‑up bids in Salta, Neuquén and Tierra del Fuego.
• In Mendoza’s provincial races, 19 of 38 Senate seats are up, with Cambia Mendoza eyeing a quorum comeback with roughly 40% of the vote while the PJ risks surrendering most of the seats it defends.
