Core Poll Findings
A Datafolha poll released on August 21 shows incumbent President Luiz Inácio Lula da Silva maintaining a lead over Senator Flávio Bolsonaro in the upcoming presidential race. In a simulated second-round runoff, Lula would obtain 47 percent of the vote against Bolsonaro’s 43 percent, within the poll’s two-point error margin. In a first-round scenario, Lula leads with 39 percent, followed by Bolsonaro at 33 percent, with Ronaldo Caiado (5 percent), Renan Santos (4 percent) and Romeu Zema (3 percent) trailing.
Campaign Context and Legal Developments
President Lula launched his re-election campaign on August 16, holding a rally at a stadium in São Paulo. The poll is the first released since the official campaign period began, when candidates may actively seek votes. It also follows two notable legal events: Brazil’s Supreme Court authorized the Federal Police to investigate Lula’s eldest son on suspicion of illicit business dealings involving the federal government, and a May revelation that Senator Bolsonaro had asked a now-jailed banker to finance a film about his father, which coincided with a dip in Bolsonaro’s poll numbers.
Data Summary
- Survey period: Datafolha began interviewing 2,058 respondents on August 18.
- Lula’s approval rating fell to 47 percent, down from 49 percent in July; his disapproval rate rose to 50 percent from 48 percent.
- The poll’s margin of error is ±2 percentage points.
Implications for the Election
The narrow gap between the two frontrunners suggests a competitive race, though the margin remains within statistical uncertainty. Lula’s declining approval alongside Bolsonaro’s modest gains may reflect voter reactions to the recent investigations and the film-financing controversy. Should no candidate surpass the 50 percent threshold in the first round, a runoff—required in every presidential election since 2002—would likely pit Lula against Bolsonaro, setting the stage for a decisive second-round contest.
