The latest Datafolha survey places President Luiz Inácio Lula da Silva ahead of Senator Flávio Bolsonaro in the first round of Brazil’s 2026 presidential contest, but it offers neither side a decisive national advantage.

From the left’s perspective, Lula’s position has strengthened slightly: he rose from 39% to 40%, while Flávio Bolsonaro remained at 36%. The same account describes a runoff as a “technical tie,” with Lula on 47% and Bolsonaro on 45%, inside the poll’s two-point margin of error.¹ Lula also led a separate second-round simulation against Ronaldo Caiado, 46% to 44%.

The right’s account reports the same topline numbers but emphasizes the pressure on both frontrunners to secure tactical support before the first round. It says the stable standings have “increased pressure” on the two leading campaigns for voto útil—strategic voting intended to avoid splitting support among candidates.²

The gap between the two readings is therefore one of emphasis rather than underlying data. Lula’s supporters can cite his numerical lead and one-point gain; Bolsonaro’s side can point to a contest close enough that the projected runoff cannot establish a clear leader. Other candidates remain well behind: writer Augusto Cury polled 5%, Caiado 4%, and Renan Santos 3%, according to both reports.

The right-leaning report also identifies three campaign themes that it says influenced the week: a reduced focus on the Supreme Federal Court dispute, debate over a proposed 15% Bolsa Família increase, and claims of foreign involvement in the campaign. It notes that the government rejects the opposition’s characterization of the welfare-policy debate and its approach to organized crime.²

Datafolha surveyed 2,002 voters and registered the poll with Brazil’s electoral authorities under BR-00304/2026.¹
