Recent AtlasIntel polling conducted March 18-23 reveals President Luiz Inácio Lula da Silva ahead of Senator Flávio Bolsonaro at 45.9% to 40.1% in first-round voting intentions for the October 4 election, with Renan Santos trailing far behind at 4.4% and other governors like Ronaldo Caiado and Romeu Zema fragmented below 4%, driving trader consensus toward Flávio as the clear second-place frontrunner. Flávio's surge from mid-30s in prior surveys stems from Jair Bolsonaro's endorsement, the right-wing field's consolidation after Ratinho Júnior's March 23 withdrawal, and Lula's slipping approval amid economic headwinds. Upcoming debates and regional primaries could further test this tight matchup, where undecideds and turnout in swing Northeast states remain pivotal.
