Recent polling in Rio Grande do Sul shows a fragmented Senate field for the two seats, with Marcel van Hattem (Novo), Manuela d'Ávila (PSOL), Ubiratan Sanderson (PL), Paulo Pimenta (PT), and Germano Rigotto (MDB) appearing technically tied or within narrow margins in July surveys. National polarization shapes voter attention, as candidates link their platforms to federal issues including administration criticism, democratic safeguards, education policy, and climate responses. The open contest stems from retiring incumbents and a broad candidate list, keeping first-place probabilities closely matched near 20-25% in trader assessments. Separation could arise from intensified campaign events, coalition endorsements, or late polling shifts before the October vote.
