Flávio Bolsonaro holds a commanding position in trader assessments for first place in Rio Grande do Sul during the October 25 presidential runoff, reflecting the state’s consistent right-wing tilt and his stronger-than-expected first-round showing. Pre-election surveys in the state already indicated a double-digit advantage for him over incumbent President Lula in a head-to-head matchup, consistent with broader regional patterns favoring conservative candidates. The right’s first-round gains in RS, including the gubernatorial victory of Liberal Party candidate Luciano Zucco and Senate wins, reinforced this dynamic and aligned with national momentum behind the PL ticket. Factors such as evangelical voter preferences, economic messaging on fiscal restraint, and vote migration from eliminated right-leaning contenders further support the current consensus. Late developments that could narrow the gap include shifts in turnout among Lula’s base or unexpected campaign events, though historical state-level voting patterns and recent polling margins suggest limited scope for reversal.
