Flavio Bolsonaro maintains a commanding lead in Paraná polling for the October 4 first-round presidential vote, with recent surveys from Real Time Big Data, Quaest, and AtlasIntel placing him between 40% and 53% against Lula’s 26-34% and single-digit shares for names such as Augusto Cury, Renan Santos, Ronaldo Caiado, and Romeu Zema. The state’s conservative electorate, elevated disapproval of the federal administration, and consistent name recognition tied to prior PL support underpin trader consensus on his first-place finish. Remaining uncertainty centers on the sizable undecided bloc and any last-minute shifts in turnout or campaign events before election day, though no comparable contender has closed the gap in published data.
