Flávio Bolsonaro holds a commanding position in trader consensus for first place in Mato Grosso do Sul's second-round presidential vote, driven by his 58.6% share in the October 4 first round against incumbent Luiz Inácio Lula da Silva's 34.7%. Multiple late-September polls in the agricultural state consistently showed the PL senator ahead by double digits in both first- and second-round simulations, reflecting sustained regional preference for the right-wing candidate amid national results that advanced the pair to the October 25 runoff. Historical voting patterns in Mato Grosso do Sul and strong performance across Center-West states reinforce this positioning. Scenarios that could still shift outcomes include unusually high turnout shifts or late campaign developments before the runoff.
