Recent polling places incumbent President Luiz Inácio Lula da Silva and Senator Flávio Bolsonaro as the clear frontrunners for Brazil’s October 4 first round, with Lula typically in the low-to-mid 40s and Flávio in the low-to-mid 30s among valid votes. Other candidates, including Augusto Cury, Ronaldo Caiado, Renan Santos, and Romeu Zema, remain in single digits and show little momentum. Runoff simulations between the two leaders are statistically tied or show minimal edges that flip across houses, underscoring a polarized electorate and high undecided or blank ballot shares. No candidate is expected to reach an outright majority, so the top two advance to the October 25 runoff. Late campaign events, including debates and turnout among swing voters, could still shift the final ordering before the first-round vote.
