Overview

• Argentina will use the state-printed Boleta Única de Papel for the first time nationwide to renew 127 seats in the Chamber of Deputies and 24 in the Senate on Sunday, October 26.
• Voting shifts from a traditional closed room to classroom cabinas where each elector marks one box per category on a single ballot and then folds and deposits it as instructed.
• In Mendoza, authorities confirmed three officials per table, two facing cabinas, color-coded and labeled urns (celeste for national, verde for provincial), and large wall posters with real candidate lists.
• Mendoza urged residents to recheck the register after nine schools were reassigned; the province reports 1,523,848 eligible voters across 4,445 tables in 644 schools, with more than 51,000 first-time youth voters.
• The national electoral court ruled against reprinting ballots in Buenos Aires after José Luis Espert withdrew, so his image remains on the BUP even as Diego Santilli leads La Libertad Avanza’s list; voters can verify polling places via padron.gob.ar, 0800-999-7237, Mi Argentina and the WhatsApp chatbot Vot-A.
