Derrite and André do Prado Win São Paulo Senate Seats

Overview

• Guilherme Derrite (PP) and André do Prado (PL) were elected to the two Senate seats for São Paulo, with the Tribunal Superior Eleitoral reporting about 90% of ballots counted on Sunday, October 4 showing Derrite at roughly 30.7% (≈11.96 million votes) and Prado at roughly 29.4% (≈11.44 million votes).
• Simone Tebet (PSB) and Marina Silva (Rede), candidates backed by President Lula, finished third and fourth with about 19.1% and 18.0% respectively and failed to win seats.
• Ricardo Salles withdrew his candidacy late in the campaign and publicly endorsed Derrite and Prado, but his name remained on ballots because the electoral deadline had passed and the São Paulo regional court fined him R$10,000 during the cycle for early propaganda and derogatory content against Prado.
• The two winners ran on conservative platforms tied to security and right-wing networks and counted on active backing from Governor Tarcísio and figures in the PL such as Flávio Bolsonaro, factors credited by multiple outlets for mobilizing votes across the state.
• The result strengthens São Paulo’s conservative delegation in the federal Senate and could reshape oversight and legislative dynamics in Brasília, with potential effects on the Lula administration’s ability to pass or block measures and on future oversight actions involving the Supreme Court.
