BRASIL Datafolha poll shows strong turnout intent ahead of Brazil’s runoff
The survey found that 96% of Brazilian voters say they plan to cast a ballot on October 25. Another 1% said they do not intend to vote, while 3% remain undecided.
A Datafolha survey reported by O Globo and Folha de S.Paulo found that 96% of Brazilian voters say they intend to vote in the October 25 runoff. Another 1% said they do not plan to go to the polls, and 3% said they have not decided yet.
Among voters who say they support Lula, 98% said they expect to vote and 2% said they are still undecided. The same figures were recorded among supporters of Flávio Bolsonaro, with 98% saying they plan to vote and 2% still unsure.
Among respondents who said they plan to cast a blank or null ballot or back no candidate, 63% said they intend to show up, 23% said they likely would not vote, and 13% said they remain undecided.
According to Folha de S.Paulo, the poll surveyed 2,520 voters from Tuesday the 13th to Wednesday the 14th through face-to-face interviews in 153 municipalities. The margin of error is two percentage points, and the confidence level is 95%. The poll was commissioned by Folha and registered with Brazil’s Superior Electoral Court under code BR-00466/2026.
For the group that does not intend to vote or is still undecided, Datafolha said the most common reason was uncertainty about the candidates, cited by 47%. That was followed by doubts between the two contenders, at 27%, and dislike of both candidates, at 20%. Another 15% cited obstacles or practical impediments.
Other reasons appeared at lower levels: not liking elections or not feeling like voting, 11%; being out of town, 7%; having to work that day, 4%; not being required to vote because of age, 4%; saying they would cast a blank ballot, 3%; not having voted in the first round, 2%; distance from the polling place, 2%; not knowing the polling location, 1%; health problems, 1%; and the view that the winner is already decided, 1%.
According to O Globo, turnout in the first round of the presidential election was affected by an abstention rate above 21%, representing more than 33 million voters who did not go to the polls.
