On Sunday, October 26, Argentina renews 127 seats in the Chamber of Deputies and 24 in the Senate across eight districts, debuting the Paper Single Ballot. The vote is pivotal for Javier Milei's government balance. Provisional results start at 9 p.m.
The 2025 national legislative elections occur on Sunday, October 26, with voting from 8 a.m. to 6 p.m. nationwide. 127 deputies are elected across all provinces, including 35 in Buenos Aires, 9 in Córdoba, 5 in Santa Fe, and 5 in Mendoza. For the Senate, eight districts—Ciudad de Buenos Aires, Chaco, Entre Ríos, Neuquén, Río Negro, Salta, Santiago del Estero, and Tierra del Fuego—renew 24 seats, with three per district: two for the majority and one for the first minority. Terms begin December 10, lasting four years for deputies and six for senators.
The highlight is the debut of the Paper Single Ballot (BUP), replacing traditional party ballots. Divided into horizontal rows by category (deputies and senators) and vertical columns by political groups, it is marked in booths with screens, without a dark room or envelopes; it folds and goes directly into the urn. Vote types include affirmative, null (for multiple marks or damage), blank (valid but uncounted), and challenged (for judicial review).
The electoral ban runs from 8 a.m. Friday, October 24, to 9 p.m. Sunday, prohibiting campaigns, polls, alcohol, and gatherings near polling stations. Table authorities receive up to 80,000 pesos (40,000 for service plus 40,000 for training). La Libertad Avanza's officialism seeks more seats, while Unión por la Patria holds the first minority; UCR, PRO, and Coalición Cívica risk many.
Pre-election, Javier Milei considers reshuffling the Cabinet afterward, weighing support for Guillermo Francos or promotion of Santiago Caputo, plus alliances with PRO, UCR, and governors. Analyst Lucas Romero warns the government needs to 'build governability' given its fragile base. TN and Perfil provide live coverage with provincial maps.
