Recent national polls show Flávio Bolsonaro consolidating right-wing support in the low-to-mid 30s or low 40s for Brazil’s October 4 first round, often within the margin of error of incumbent Lula and reflecting steady gains among evangelicals, higher-income voters, and southern states. Late-September surveys from Datafolha, Quaest, and others indicate a technical tie or narrow Lula edge in first-round scenarios after earlier volatility tied to campaign controversies, while second-round simulations frequently show statistical dead heats. This positioning, combined with the Liberal Party candidate’s focus on his father’s base and regional strongholds, underpins trader consensus around the 42-45% bin as the most probable outcome range.
