Recent polling from late September shows a fragmented race for the two Acre Senate seats, with Gladson Cameli (PP), Márcio Bittar (PL), Mara Rocha (Republicanos), and Jorge Viana (PT) clustered within a few points in combined first-and-second vote tallies. The latest Quaest survey placed Cameli at 19%, Bittar at 14%, Rocha at 13%, and Viana at 12%, while earlier Data Control and Real Time Big Data releases indicated similar narrow gaps and shifting first-place edges. With voters selecting two distinct candidates and only days until the October 4 election, the absence of a dominant frontrunner sustains tight implied probabilities for first place. Declining undecideds and stable party positioning have kept the field competitive without producing decisive separation.
