Datafolha: with Lula and Flávio in the 2nd round, 10% would vote blank/null and 1% don’t know
The Datafolha survey released this Saturday, 7th, shows that 10% of voters would vote blank or null and 1% would not know who to vote for in the second round scenario between Lula and Flávio Bolsonaro in this year’s presidential election.
The numbers looked like this:
- Lula (PT) – 46% (it was 51% in December 2025);
- Flávio Bolsonaro (PL) – 43% (it was 36% in December 2025);
- White/null/none – 10% (it was 12% in December);
- They don’t know – 1% (it was 1% in December).
In the second round dispute, Lula’s advantage over Flávio fell from 15 to 3 points. The son of former president Jair Bolsonaro stands out among evangelicals, southerners and residents of the North/Central-West.
Datafolha interviewed 2,004 voters in 137 municipalities from Tuesday to Thursday this week. There is a margin of error of plus or minus two percentage points.

Lula has 45% against Ratinho Júnior’s 41% in the second round; 46% against Eduardo Leite’s 34% in the second round; in addition to 46% against 36% for Ronaldo Caiado, also in the second round evaluation.
