Overview

• Parties closed and filed their slates nationwide for the 26 October elections, with late twists including a UCR split in Buenos Aires City that sent Facundo Manes and Martín Lousteau to separate tickets and a last‑minute Peronist unity list in Santa Fe led by Caren Tepp with Agustín Rossi second.
• La Libertad Avanza’s ballots were tightly curated under Karina Milei to emphasize loyalty and cohesion, mixing sitting officials with outsiders and drawing in PRO figures such as Patricia Bullrich.
• President Javier Milei will present LLA’s national candidates at a rally in Junín on Tuesday, formally launching the ruling coalition’s campaign in Buenos Aires province.
• The government is mobilizing poll watchers at scale, targeting 40,000 fiscales in Buenos Aires province and 100,000 nationwide to oversee the September and October votes.
• The lower house is set to meet Wednesday to consider four presidential vetoes affecting pension hikes, the pension moratorium, a disability emergency and an emergency for Bahía Blanca, a showdown that parties see as a pre‑campaign test.
