Recent polling from mid-September shows Gladson Camelí (PP) leading Senate intentions in Acre at 24%, followed closely by incumbent Marcio Bittar (PL) at 21%, with Jorge Viana (PT) and Mara Rocha (Republicanos) tied at 15% each in a consolidated two-vote scenario. This tight clustering among the top four contenders, just nine days before the October 4 first-round vote for two seats, sustains trader uncertainty over second place. Camelí's recent resignation from the governorship to run and Bittar's re-election bid anchor their positions, while Rocha and Viana draw support from their respective coalitions. Minor candidates like Petecão and Velloso register single digits, limiting their upside for the runner-up spot. Any late shifts in turnout among key voting blocs or campaign momentum could separate the field before ballots close.
