Teresa Surita (MDB) holds the clearest lead for first place in Roraima’s October 4 Senate election, backed by consistent polling edges of roughly 20-25% in recent surveys from institutes such as Real Time Big Data, Eficaz, and Quaest. Her extensive record as five-term Boa Vista mayor and two-term federal deputy, combined with a declared patrimony exceeding R$8 million and a broad MDB-PDT alliance, has translated into stronger voter recognition than rivals. Nicoletti (PL) trails at lower double digits, with Helio Bolsonaro and Chico Rodrigues further behind amid fragmented fields. Late-campaign focus on STF accountability and state infrastructure has reinforced Surita’s positioning, while the two-seat, two-vote system keeps outcomes sensitive to turnout and preference splitting among the remaining 11 registered candidates.
