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.
