New Poll Shows Close Race in Brazil's Presidential Runoff

A new poll conducted by BTG/Nexus has produced the first detailed snapshot of Brazil's presidential runoff, showing Flávio ahead with 52% of voting intentions compared with Lula's 48%.

The survey is significant because it is the first to be released since the conclusion of the first round, offering an early indication of how the contest may unfold.

Under Brazil's electoral system, a runoff takes place when no candidate secures an absolute majority in the first round, with the top two finishers advancing to a final head-to-head vote.

Alongside the headline figures, the poll also examined how support from eliminated first-round candidates is being redistributed between the two remaining contenders.

The candidates referenced, Cury, Caiado, Renan and Zema, all stood in the first round but failed to qualify for the runoff.

Analysts often monitor this kind of vote transfer closely, as it can reveal underlying ideological or regional alignments that shape the final outcome.

The available summary does not specify the exact breakdown of how each candidate's electorate is dividing its support, though the overall trend favours Flávio at this early stage.

The release of the BTG/Nexus poll comes amid a broader wave of electoral surveys expected this week, with two further major polls — Quaest and Datafolha — due to be published.

Both firms are well established in Brazilian political polling and are closely watched by analysts, campaign teams and the public for signs of shifting momentum.

The timing of these releases remains a point of anticipation, as each new survey has the potential to influence public perception of the race's trajectory.

With just four percentage points separating the two candidates in the BTG/Nexus poll, the contest appears tight, though it remains early in the runoff campaign.

Polling organisations in Brazil typically conduct multiple surveys throughout a runoff period, allowing for comparison and the identification of consistent trends rather than relying on a single data point.

As additional polls from Quaest and Datafolla are released this week, observers will be looking to see whether they confirm the narrow lead suggested by BTG/Nexus or reveal a different pattern.

Ultimately, the only definitive measure of voter preference will come from the official runoff vote itself, which will determine Brazil's next president.
