Overview

• Argentina holds national legislative elections on Sunday, October 26, with the Boleta Única de Papel implemented across the country.
• Mendoza will use two distinct paper ballots—national and provincial—differentiated by size and color backs (celeste and green) to limit errors.
• The province replaces the traditional voting room with cabins facing table authorities, adds a third table official, provides indelible pens, and labels separate urns.
• Polling sites in Mendoza will display large sample ballots and step‑by‑step signage, with an accessible cabin positioned in the most reachable area of each school.
• Mendoza reports 1,523,848 registered voters across 4,445 mesas in 644 schools, nine of which were removed, while the CNE published the definitive roll and confirmed Diego Santilli to head LLA’s Buenos Aires list without reprinting ballots showing José Luis Espert.
