Vice-governor Celina Leão (Progressistas) appears ahead in the race for government of the Federal District (DF) in the 2026 elections, according to a survey released this Thursday (30) by the Paraná Research Institute.
The study shows a fierce dispute with former governor José Roberto Arruda — who, by decision of the Superior Court of Justice (STJ), had upheld the sentence that makes him ineligible due to administrative improbity in one of the processes linked to Operation Pandora’s Box —, and who comes in second place in voting intentions.
The survey interviewed 1,506 voters between October 23 and 27, 2025. The margin of error is plus or minus 2.6 percentage points, and the confidence level is 95%.

In the first scenario, Celina Leão has 32.2% of voting intentions, while Arruda registers 29.8%.
Next come Leandro Grass (11.8%), Ricardo Cappelli (6.4%) and Paula Belmonte (6.0%).
Among those interviewed, 8.6% said they would vote blank or null, and 5% said they did not know or preferred not to answer.
Scenario 2: Celina extends her lead
When the number of candidates is reduced, Celina Leão opens up an advantage and reaches 36.9%, against 32.7% for Arruda.

The share of blanks and nulls is 10.2%, and 5% of voters did not respond.

Celina would beat Grass in a direct confrontation

In this case, 11.1% would vote blank or null, and 6.5% did not know how to give their opinion.
