Flávio Bolsonaro holds a strong trader consensus edge heading into the October 25 runoff, driven by his first-round performance on October 4 where he secured roughly 47% of the vote to Lula’s 45%, exceeding pre-election polling expectations and consolidating support from other right-leaning candidates. Recent national surveys, including Datafolha, Quaest, and Futura, show the race as a statistical tie or slight Flávio advantage in valid votes, with his leads among evangelicals, southern and southeastern voters, and men offsetting Lula’s strengths in the Northeast and among lower-income groups. Lula’s high rejection rate near 46% and the 80-year-old incumbent’s challenges in mobilizing abstainers from the first round further shape positioning, while the three-week campaign window offers limited time for major shifts before voters decide.
