Recent polling from Quaest, AtlasIntel, and Datafolha places Flávio Bolsonaro in the mid-to-high 30s or low 40s for the October 4 first round, statistically close to Lula amid a polarized contest. Flávio has consolidated much of the right as Jair Bolsonaro’s eldest son and PL standard-bearer, benefiting from voter concerns over public security, while Lula draws on incumbency and Bolsa Família expansions. Other conservative candidates continue to split anti-incumbent votes, and rejection rates near 47 percent for both frontrunners limit consolidation. A final pre-election debate and late shifts among undecided or blank voters remain the main variables that could push Flávio’s share outside the current 39-45 percent cluster favored by traders.
