The Rondônia Senate race for the two federal seats remains tightly contested in trader assessments due to a crowded field of 10+ officially registered candidates and fragmented early polling that shows no single contender consistently leading first-place intentions. Recent legal resolutions clearing Acir Gurgacz (PDT) to run after prior ineligibility challenges have expanded the competitive set alongside established names such as Dr. Fernando Máximo (PL) and Bruno Scheid (PL), who topped July surveys with Máximo at 19% in consolidated first-and-second-vote scenarios and higher shares in stimulated PL-focused polling. The two-seat structure encourages vote-splitting strategies within parties like PL while leaving the second spot and overall ordering highly sensitive to turnout, regional alliances, and late campaign momentum. Upcoming party conventions, additional statewide surveys, and any shifts in voter priorities around economy or security could quickly reorder preferences ahead of the October vote.
