Overview
- The Oct. 4 first-round vote left Omar Aziz with roughly 39–40% of valid votes and Professora Maria do Carmo with about 24–25%, sending both to a runoff on October 25.
- Aziz ran with a broad pro‑government coalition linked to President Lula and framed his bid as continuity with federal ties.
- Professora Maria do Carmo represents the PL’s bolsonarist field and entered the race as a right‑aligned challenger backed by Flávio Bolsonaro’s network.
- Third‑place governor Roberto Cidade and other eliminated candidates, notably David Almeida, hold blocs of voters both runoff contenders now need to win.
- Voters decided the first round on local issues such as health, education, the environment and proposals to expand mineral exploration, and those topics plus endorsements and party resources will determine the outcome on Oct. 25.
