Datafolha, Brazil’s most prominent opinion‑polling firm, unveiled a new presidential preference poll on September 11, 2024, just days after a political crisis engulfed the Supreme Federal Court (STF). The timing underscores the volatile environment in which the nation’s 2026 presidential election is shaping up, pitting incumbent President Luiz Inácio Lula da Silva against former President Jair Bolsonaro and several minor candidates.
Poll release and methodology
The poll, released publicly on the same day, follows Datafolha’s standard methodology of face‑to‑face interviews with a nationally representative sample of eligible voters. While the exact sample size and margin of error were not disclosed in the brief report by correiobraziliense.com.br, the firm traditionally conducts surveys with roughly 2,000 respondents, yielding a typical error range of plus or minus three percentage points.

According to the outlet, the survey was commissioned by the pollster itself, a routine practice that ensures independence from partisan interests. The poll’s findings are expected to provide a snapshot of voter sentiment at a moment when the country’s institutional balance is under scrutiny.
Political backdrop and stakes
Brazil’s political landscape remains deeply polarized. President Lula, a left‑wing leader who returned to office in 2023, has focused his second term on social programs, economic recovery, and restoring Brazil’s international standing. Bolsonaro, a right‑wing former president who served from 2019 to 2022, has built a campaign around law‑and‑order rhetoric and criticism of what he terms “leftist overreach.”
The recent STF crisis, which unfolded earlier in the week, involved a series of high‑profile confrontations between the court and political actors over the legitimacy of certain judicial decisions. While details vary across reports, the episode has heightened public concern about the separation of powers and the rule of law—issues that are likely to influence voter preferences.
Analysts note that any shift in public opinion captured by the new Datafolha poll could reshape campaign strategies. If Lula’s approval remains robust, his administration may press forward with its agenda, while a dip could embolden Bolsonaro’s coalition to intensify attacks on the government’s policies.
Opposition parties have already called for a transparent investigation into the STF events, arguing that the judiciary’s credibility is essential for democratic stability. Meanwhile, civil society groups warn that prolonged institutional conflict could erode trust in Brazil’s democratic institutions ahead of the 2026 elections.
International observers are watching closely, as Brazil’s political trajectory has ramifications for regional trade, climate policy, and the broader Latin American balance of power. A stable electoral outcome is seen as pivotal for maintaining investor confidence and for Brazil’s role in multilateral forums such as the G20 and the United Nations.
Datafolha’s latest poll, released amid the court turmoil, will be dissected by campaign teams, analysts, and foreign diplomats alike. While the exact numbers remain to be published in full, the poll’s emergence signals that political actors are keen to gauge the electorate’s mood before the election calendar intensifies later this year.
