Recent polling in Rio Grande do Sul shows a tight first-round contest between PDT candidate Juliana Brizola, backed by President Lula, and PL candidate Luciano Zucco, aligned with Senator Flávio Bolsonaro, with the pair trading narrow leads or tying within margins of error. Multiple August surveys, including Real Time Big Data and Quaest, place Brizola between 23-38% and Zucco between 26-32%, while incumbent-aligned MDB candidate Gabriel Souza trails in third at 9-19%. High undecided and blank/null shares exceeding 25-30% in most releases, combined with 39% of voters indicating they may still switch preferences, sustain volatility. Trader consensus reflected in current market pricing aligns with Brizola’s modest edges in several head-to-head second-round simulations, though the race remains open ahead of the October 4 first round. Further campaign momentum, coalition consolidations, or shifts among undecided voters could widen the gap between the frontrunners.
