Runoff Poll Shows Lula Ahead of Flavio Bolsonaro
A poll conducted by CNT/MDA between June 10 and June 14, 2026, indicates that former President Luiz Inácio Lula da Silva would receive 49.3 % of the vote in a hypothetical runoff against Senator Flávio Bolsonaro, who would obtain 36.8 %. The poll’s margin of error is ± 2.2 percentage points. Conducted in mid-June, the poll offers a snapshot of voter preferences approximately four months before the scheduled October ballot. The findings were reported by Reuters on June 16.
Election Context and Candidate Profiles
The poll refers to Brazil’s general elections scheduled for October 2026, in which a second round would be required if no candidate secures an outright majority in the first round. Lula, the incumbent president, is seeking re-election. Flávio Bolsonaro, a senator from Rio de Janeiro, is the son of former President Jair Bolsonaro, who held office from 2019 to 2022. The survey was conducted roughly four months before the October vote.
Poll Methodology and Sample
CNT/MDA surveyed 2,002 eligible voters across 143 Brazilian municipalities. Respondents were selected to reflect the national adult population, though the exact sampling technique is not detailed. The reported margin of error of 2.2 points applies to each candidate’s share, indicating that the true support levels could vary within that range.
Results Compared to April Survey
In an earlier poll conducted in April, Lula’s projected runoff support stood at 44.9 % while Flávio Bolsonaro’s was 40.2 %. The June figures therefore show an increase of 4.4 percentage points for Lula and a decrease of 3.4 points for Flávio. The swing of 4.4 points toward Lula and 3.4 points away from Flávio over a two-month interval reflects a measurable shift in the surveyed electorate. The gap between the two candidates widened from 4.7 points in April to 12.5 points in June, reflecting a shift in respondents’ expressed preferences.
Implications for the October Election
Assuming the runoff scenario reflects voter behavior in a second round, Lula’s lead exceeds the poll’s margin of error, suggesting a statistically significant advantage. The gap also surpasses the combined margins of error for both candidates, reinforcing the robustness of the lead. Thus, even accounting for sampling variability, Lula retains a clear advantage. The data imply that, should a runoff occur, Lula would retain a sizable share of the electorate relative to Flávio Bolsonaro.
Conflicting Reports & Gaps
