Flávio Bolsonaro’s commanding lead in Paraná for the October 25 second-round presidential contest stems from his decisive first-round performance in the state, where he captured nearly 60% of valid votes against Lula’s 31%, and from multiple pre-election surveys showing him ahead by 20–30 points in runoff matchups. Paraná’s electorate has consistently favored the PL candidate across recent polls, reflecting regional voting patterns that delivered large margins in key cities and rural areas during the October 4 balloting. With the second round now limited to the two finalists and most right-leaning first-round support consolidating behind him, traders price in minimal room for reversal absent major late developments such as turnout shifts or unforeseen national events.
