Mara Rocha secured the second Senate seat for Acre in the October 4, 2026, election, finishing with approximately 17.95% of valid votes behind Marcio Bittar’s leading 25.59%. Official tallies from the Tribunal Superior Eleitoral placed her ahead of competitors including Gladson Cameli, whose substantial vote share was recorded as annulled sub judice due to a prior candidacy ruling under the Ficha Limpa law. Pre-election polling had shown a tighter race among several candidates, yet Rocha’s performance consolidated support in key municipalities and benefited from the majoritarian rules allocating the two available seats to the top eligible vote-getters. This outcome aligns with trader consensus reflecting the final certified results, though any lingering judicial reviews of candidacies could still affect formal certification timelines.
