Overview
- The first-round vote held on Sunday, Oct. 4, drew just over 125.2 million voters and the Tribunal Superior Eleitoral supplied the nationwide tallies that news outlets published in the hours after the polls closed.
- Agência Brasil compiled a state-by-state list showing outright winners for many governorships and the two most-voted senate candidates per state, including Rui Costa and Jaques Wagner as Bahia’s elected senators and Jerônimo Rodrigues elected governor of Bahia.
- The TSE and multiple outlets reported some senatorial races called as decided before full tabulation, notably Mauro Mendes and Zé Medeiros in Mato Grosso were declared 'matematicamente eleitos' once counts neared completion.
- Local automated pages republished TSE municipal data showing geographic variation in the presidential vote, with Flavio Bolsonaro leading in many municipalities while other areas favored Lula, underlining the uneven regional map going into runoffs.
- What comes next: the TSE will complete formal confirmations and publish final protocols, and voters should expect second-round presidential and key gubernatorial runoffs that will determine the composition of state executives and influence the balance of power in the federal government.
