Recent polls indicate a statistically tied contest between incumbent President Luiz Inácio Lula da Silva and Senator Flávio Bolsonaro in simulated runoffs ahead of the October 4 first round, with Lula holding slim edges of 1–2 points within margins of error across Datafolha, Quaest, AtlasIntel, and BTG Pactual surveys. Flávio Bolsonaro carries the Liberal Party banner for the right after his father Jair Bolsonaro’s conviction and imprisonment for attempting to overturn the 2022 result, leaving the race defined by entrenched left-right polarization and high rejection rates for both leading candidates. First-round support shows Lula at roughly 37–45% and Flávio Bolsonaro at 33–43%, with smaller candidates like Augusto Cury and Ronaldo Caiado splitting the remainder. A potential October 25 runoff would hinge on turnout, coalition alignments, and any late shifts in voter sentiment amid ongoing Supreme Court tensions.
