The latest round of the Quaest poll, made public this Monday (14), added a new element to the presidential race: in a second-round simulation, Flávio Bolsonaro (PL) appears numerically ahead of President Luiz Inácio Lula da Silva (PT). It is the first such record since the start of the campaign, according to the survey itself.
What the survey shows
The scenario tested by Quaest projects a direct confrontation between the senator from Rio de Janeiro and the head of the federal executive. In this configuration, the PL lawmaker appears in a slightly higher position than the PT candidate — a reversal compared to previous rounds, which had been pointing to the president ahead.
The advantage, however, is numerical in nature and should be interpreted with caution. Since the survey's margin of error is 2 percentage points, plus or minus, fluctuations of this magnitude usually indicate a tie between the two names, rather than a consolidated lead.
How the poll was conducted
- Sample: 2,004 voters interviewed
- Collection period: between September 10 and 13
- Margin of error: 2 percentage points, plus or minus
The methodology adopted follows the standard of vote intention polls released throughout the campaign, with in-person or telephone interviews and subsequent weighting of the data by demographic and regional profile.
Why the data draws attention
Second-round simulations work as a thermometer of the degree of polarization of the electorate. When two candidates appear in an equivalent range within the margin of error, the result usually signals an electorate that is still undecided and sensitive to short-term movements, such as debates, economic agendas and image erosion.
In the specific case of this round, the fact that the advantage appears for the first time since the beginning of the campaign also suggests that the electoral scenario remains volatile. Previous polls had already indicated a narrowing between the two camps, which now translates into a slight lead for the PL representative in the projection of a possible direct clash.
What to watch going forward
Public opinion experts usually recommend that a single survey not be read as a definitive trend. The most reliable reading comes from comparing series of polls conducted by different institutes and at regular intervals.
Therefore, the next surveys will be decisive in indicating whether the movement captured now is confirmed as a structural change in the presidential race or represents merely a one-off fluctuation within a scenario of a technical tie.
Monitoring the other first- and second-round simulations, as well as the evolution of each pre-candidate's rejection rate, will help gauge the real reach of this new data in the race for the Palácio do Planalto.
