Overview

• The nationwide vote takes place Sunday, October 26, to renew 127 deputies and 24 senators in Congress.
• The definitive electoral roll is available; voters can verify their school, table and order at padron.gob.ar, via MiArgentina, or by calling 0800-999-7237, with potential site adjustments up to 48 hours before voting.
• This cycle debuts the Boleta Única de Papel under Law 27.781, which consolidates choices on one sheet where voters mark a single box, and runs without PASO after Congress suspended the primaries for 2025.
• Following José Luis Espert’s resignation, the CNE set Diego Santilli to head La Libertad Avanza’s Buenos Aires list, and ballots will not be reprinted so Espert’s image may still appear.
• Eight jurisdictions renew Senate seats this year—Salta, Chaco, Santiago del Estero, Entre Ríos, CABA, Neuquén, Río Negro and Tierra del Fuego—while several provinces, including Mendoza, also hold local or provincial contests.
