Candidates for the Senate for Roraima: Nicoletti, Teresa Surita, Helena da Asatur, Chico Rodrigues — Photo: Assessrias/Disclosure
Quaest research released this Saturday (3), the eve of the 1st round, shows how the dispute for the Senate is going in Roraima. This Sunday (4), each voter will have to vote for two candidates. Nicoletti (PL) and Teresa Surita (MDB) appear technically tied in valid votes, with 26% and 25% respectively. Helena da Asatur (PSD) comes next, with 19%.
Spontaneous search
First, Quaest asked voters who they would vote for, without showing the list of candidates. This is a spontaneous survey, and 38% of respondents did not mention a name in their response. Therefore, they are considered undecided (at the end of the report, see data from the spontaneous survey).
The results of the spontaneous survey help to measure the degree of vote consolidation. The greater the number of undecided voters the day before, the less consolidated the vote is and the greater the possibility of changes in relation to Sunday's result.
Stimulated search - valid votes
In the stimulated survey, the names and parties of the candidates are presented to the interviewees. Each voter chooses a name for the first vacancy in the Senate and another for the second.
The data below considers the votes valid. This calculation excludes blank and invalid votes and also undecided voters.

What are valid votes?
This is the way in which the TSE publishes the official results of the elections. These are the votes cast for candidates. This calculation leaves out blank and invalid votes and abstentions. To win in the 1st round, a candidate needs 50% of the valid votes plus one vote.
How does Quaest calculate valid votes?
Quaest takes into account voting intentions from the survey and the turnout profile to estimate valid votes. It is the likely voter model, which considers voters with a greater propensity to vote.

The Superior Electoral Court carried out the last check of the electronic voting systems this Saturday (3), confirming the integrity of the programs and the zeroth of the elections. On Sunday (4), 158 million Brazilians will be able to vote in the first round. The Federal Police seized more than R$26 million in cash suspected of being used in electoral crimes, while security forces will act to guarantee free access to voting locations until 5 pm.

The first round campaign ends with Lula (PT) in a technical tie with Flávio Bolsonaro (PL), who is experiencing his best moment with growth among men, evangelicals and the middle class in the Southeast, while the president faces difficulty in expanding his electorate despite an advantage among low income and young people.

The president of the TSE, minister Kassio Nunes Marques, praised electronic voting machines, reinforced the importance of voting and stated that any attempt to embarrass voters will be combatted by the Electoral Court. He announced that the last two voters in each section will receive the ballot paper and recommended that voters take a sticker with the candidates' numbers to speed up voting.

Six candidates are running for Government of Goiás in the 2026 elections, with voting in the first round scheduled for October 4th. To win in the first round, a candidate must obtain more than half of the valid votes. If none reach this level, the two most voted will compete in the second round on October 25th. On this same day, voters will also vote for state deputy, federal deputy, senator and president.

Datafolha polls released this Saturday (3), the day before the vote, show Flávio Bolsonaro (PL) ahead in the valid votes in the 1st round in São Paulo (45% x 39%), Rio de Janeiro (48% x 40%) and the Federal District (49% x 37%). Lula (PT) leads in Pernambuco with 65% x 26%. In Minas Gerais, the two are tied with 44% each. In the national survey, Lula has 45% and Flávio Bolsonaro 42%, in a technical tie. The margins of error vary between two and three percentage points depending on the state.

The president of the TSE, minister Kassio Nunes Marques, stated in a national statement that threats, harassment or attempts to interfere with the voter's will will be repressed in the first round of elections, this Sunday (4). He highlighted the security of electronic voting machines, provided guidance on necessary documents, banning cell phones in the booth and measures such as paper voting and the Your Vote Matters Program for vulnerable groups.
