Overview
- The Tribunal Superior Eleitoral began releasing official first‑round results at 17:00 BRT on Sunday, October 4, and news sites such as O GLOBO and g1 updated live dashboards in sync with those feeds.
- Dashboards show vote percentages, the share of urnas apuradas and turnout figures including abstention, blank votes and null votes so readers can track how complete the count is in real time.
- Senate contests this cycle elect two senators per state and the Federal District for 54 seats total, with the Senado Federal reporting 315 candidates competing nationwide.
- Federal and state deputies are chosen under a proportional system that uses the quociente eleitoral and quociente partidário, so final seat allocation will only be confirmed after full apuração and the Justiça Eleitoral’s quota calculations.
- If no candidate wins an absolute majority for president or a governorship, those races will go to a second round on October 25, and the live tools offer state and municipal maps plus, in some cities, results down to individual urnas to follow local outcomes such as the Paraíba senate race.
