Flavio Bolsonaro holds a strong position in Federal District first-round polling due to his role as a sitting PL senator representing the capital region and the enduring local strength of the Bolsonaro family political brand. Recent September surveys, including Correio/Opinião and Quaest, show him leading or statistically tied with incumbent President Lula, with support in the low-to-mid 30s against Lula’s similar range and single-digit figures for Ronaldo Caiado, Augusto Cury, and Renan Santos. Trader consensus at 84% for Flavio reflects the District’s conservative leanings and polarization between PT and PL voters ahead of the October 4 vote, while Lula’s 16% implied probability aligns with his national incumbency but weaker local base. Other registered candidates remain marginal in DF-specific data.
