Celina Leão (PP) leads the race for governor of Brazil's Distrito Federal with 34% of voter support [1].

The results indicate a significant lead for the incumbent as the region prepares for the 2026 elections, potentially shaping the administrative future of the capital.

According to a Quaest poll conducted from Aug. 21 to 24, Leão's 34% support [1] places her well ahead of her nearest competitors. José Roberto Arruda (PSD) follows with 20% [2], while Leandro Grass (PT) holds 13% [3].

The survey included 1,104 respondents aged 16 and older [4]. It carries a margin of error of ±3 percentage points [6] and a confidence level of 95% [7]. The poll is registered with the Superior Electoral Court under number DF-06256/2026 [8].

Other candidates trail significantly in the rankings. Paula Belmonte (PSDB) and Ricardo Cappelli (PSB) both hold three% support [11, 12]. Kiko Caputo (Novo) has two% [13], and Samara Mineiro (UP) has one% [14].

A notable portion of the electorate remains undecided or abstinent. Indecisive voters account for 14% of the sample [9], while 10% of respondents indicated they would cast blank, null, or no votes [10].

The poll was published on Aug. 25 to gauge voter intentions leading up to the gubernatorial contest in the Distrito Federal.

Celina Leão (PP) leads the race for governor of Brazil's Distrito Federal with 34% of voter support.

The current polling gap suggests Celina Leão possesses a strong baseline of support as the incumbent, but the combined percentage of undecided and blank voters—totaling 24%—remains larger than the gap between Leão and Arruda. This volatility indicates that the final outcome could shift if the leading candidate fails to capture the undecided bloc or if the opposition consolidates support.
