Datafolha — President - First Round

First-round stimulated vote intention; total-response basis. MOE ±2 pp; confidence 95%. Blank/null/none 5%; undecided 2%. Retain original rounded figures without normalization. Published 2026-10-01 19:05 America/Sao_Paulo = 2026-10-02 00:05 Europe/Zagreb. Folha reports n=2506 and fieldwork 2026-09-28 to 2026-10-01; CNN currently reports n=2002 and Transmissao Politica reports an earlier fieldwork end, so Folha takes precedence.
