In Roraima's October 2026 Senate contest for two seats, the 2nd-place market remains tightly contested due to a fragmented field of more than two dozen candidates backed by different parties and alliances. Recent party conventions have formalized nominations including Chico Rodrigues of the PSB as incumbent, Helena da Asatur of the PSD, Rogério Miranda of the Christian Democracy party, and others such as Pastor Isamar and Bartô Macuxi, with additional support emerging for figures connected to broader national networks. This wide dispersion of support, combined with limited statewide polling and shifting local coalitions, sustains even implied probabilities across leading options. Developments such as further endorsements, candidate withdrawals, or intensified campaign activity in the coming weeks could consolidate votes and widen gaps among contenders.
