Flávio Bolsonaro's commanding position in Roraima stems from entrenched regional preferences for the Liberal Party candidate, who polls at 52% in an August 27 Quaest survey for the state compared with Lula at 17% and single-digit support for rivals such as Renan Santos, Ronaldo Caiado, and Augusto Cury. Roraima's electorate has consistently favored Bolsonarista positions in prior cycles, and Flávio's role as the standard-bearer for that movement after his father's ineligibility reinforces this base ahead of the October 4 first round. Traders price this dominance at 98% implied probability, consistent with the state's small electorate and limited national polling penetration. Scenarios that could narrow the gap include late vote consolidation behind other right-wing names, shifts among undecided voters, or unusually high blank or invalid ballots, though no recent developments indicate momentum for such changes.
