Datafolha poll shows narrowing lead for Lula over Flavio Bolsonaro

AI-summarized · Neutrality-checked

A Datafolha poll conducted between September 1-2 indicated that President Luiz Inacio Lula da Silva’s lead over Senator Flavio Bolsonaro narrowed ahead of the October election. In a potential runoff, Lula held 46% of the vote compared to 44% for Bolsonaro, a decline from the 47% to 43% margin recorded in mid-August. This shift mirrored trends observed in recent polls from Quaest and AtlasIntel/Bloomberg, which also showed a tightening race. In the first-round scenario, Lula led with 38% while Bolsonaro followed with 33%.

Consequences

If no candidate secures more than 50% of valid votes in the first round, the two frontrunners will advance to a runoff election. This procedure has been utilized in every presidential election in Brazil since 2002.
