Core Event: Polls Show Narrow Lead for Incumbent Lula
On September 24, 2026, Datafolha released a poll indicating that in a simulated runoff Lula would receive 47 % of the vote against 45 % for Senator Flávio Bolsonaro. The margin of error is 2 percentage points, making the result a technical tie. In a first-round scenario the same survey gave Lula 40 % and Bolsonaro 36 %. Datafolha surveyed 2,002 people between September 22-23.
Background & Context
Lula, 80, is seeking a fourth non-consecutive term after serving from 2003-2010 and returning in 2023. Flávio Bolsonaro, 45, is the eldest son of former President Jair Bolsonaro, who is serving a 27-year prison sentence for attempting to overturn the 2022 election. Jair Bolsonaro was barred from running in 2026, prompting Flávio to launch his campaign in July 2026 with his father’s backing. The election will be decided in a first round on October 4, 2026, with a runoff on October 25 if no candidate exceeds 50 % of valid votes.
