The São Paulo Senate race for two seats remains tightly contested ahead of the October 4 election, with recent Quaest polling showing Guilherme Derrite (PP), Marina Silva (Rede), and Simone Tebet (PSB) in a technical tie at 11-12% each when combining first and second preferences. Derrite, backed by Governor Tarcísio de Freitas’s coalition, competes directly against the ex-ministers aligned with Fernando Haddad’s gubernatorial ticket. High undecided rates (27%) and blank/null intentions (18%) continue to compress separation among frontrunners, while lower-polling names such as André do Prado and Ricardo Salles trail further back. Campaign events linking the Senate hopefuls to their respective state tickets and occasional exchanges over policy records have yet to shift the narrow margins materially.
