Flávio Bolsonaro has emerged as the leading right-wing contender after receiving his father Jair Bolsonaro’s endorsement late last year, allowing him to consolidate conservative support in a fragmented field ahead of the October 4 first round. Recent Datafolha and Quaest surveys show President Luiz Inácio Lula da Silva holding a narrow first-round lead while Flávio trails closely behind, with other right-leaning figures such as Ronaldo Caiado and Romeu Zema drawing only low single-digit shares. This dynamic has driven trader consensus toward Flávio for second place, as opposition voters coalesce around the Liberal Party candidate. Lula’s campaign focuses on his incumbency and policy record, yet economic pressures and the polarized contest keep the race tight. Upcoming polling releases and potential endorsements from state governors remain key variables that could shift positioning before the vote.
