Luiz Inácio Lula da Silva holds a lead over Flávio Bolsonaro in a new Datafolha poll for Brazil's presidential second round [1].

The results arrive amid significant political instability for the Bolsonaro campaign following the emergence of a scandal involving audio recordings of Daniel Vorcaro. This shift in voter sentiment suggests a potential change in momentum as the candidates navigate the fallout from these revelations.

According to the survey released Friday, Lula maintains 47% of voter support [1]. Flávio Bolsonaro follows with 43% [1]. This creates a gap of five percentage points between the two candidates [3].

The poll was designed to assess how voter intentions have shifted following the "Dark Horse" case and the specific audio recordings involving Vorcaro, which have impacted Flávio Bolsonaro's pre-candidacy [5]. The data indicates that the scandal has created a window of opportunity for Lula to widen his lead.

Other data from the survey suggests that Michelle Bolsonaro would perform similarly to Flávio Bolsonaro in a second-round matchup against Lula [6]. This indicates a consistent baseline of support for the Bolsonaro family's political platform, regardless of the specific candidate chosen.

Analysts said that the five-point difference [3] reflects a volatile electorate. The current lead for Lula comes as the campaign enters a critical phase where the impact of legal scandals and personal conduct often dictates the final outcome in Brazil's polarized political landscape.

The polling shift reflects the immediate impact of the Daniel Vorcaro audio scandal on Flávio Bolsonaro's viability. While the Bolsonaro base remains relatively stable—as evidenced by Michelle Bolsonaro's similar polling numbers—the lead held by Lula suggests that the scandal may be alienating undecided or swing voters who are sensitive to ethics-related controversies.
