Derrite and André do Prado Elected Senators for São Paulo

Overview

• With vote counts confirmed late Sunday, Oct. 4, Guilherme Derrite (PP) and André do Prado (PL) won São Paulo’s two Senate seats with roughly 30.7% and 29.3% of the vote respectively.
• Their victories consolidate the slate backed by Governor Tarcísio de Freitas and reflect late‑stage realignments on the right that reduced vote splitting, including Ricardo Salles’s withdrawal and endorsement days before the election.
• Derrite ran a hard‑line security campaign tied to Bolsonarismo and has already pledged active support for Flávio Bolsonaro, while Prado ran as Tarcísio’s ‘right‑hand’ and benefited from PL party coordination.
• The result blocks President Lula’s effort to add two allied senators from São Paulo, as Simone Tebet (PSB) and Marina Silva (Rede) finished third and fourth with about 19% and 18% of the vote.
• The two senators will take office in 2027 for eight‑year terms, shifting Senate math in ways that could affect oversight of the Supreme Federal Court and possible impeachment or investigatory processes.
