**Gustavo Gayer (PL) holds the clearest edge for second place in Goiás’s October 4 Senate contest, where voters select two candidates and Gracinha Caiado (União) leads polls by a wide margin.** The most recent Paraná Pesquisas survey (August 14–17) shows Gayer at 27.1% on the combined first-and-second-preference measure, ahead of Vanderlan Cardoso (PSD) at 21.4%, Zacharias Calil (MDB) at 19.5%, and Gustavo Mendanha (PRD) at 16.3%, with the others trailing further. This positioning reflects Gayer’s stronger consolidated support among men and right-leaning voters, his rising profile as a federal deputy, and the PL’s organizational push following candidate registrations. The race remains fluid because of high undecided shares, voters’ ability to split tickets, and several mid-tier contenders drawing overlapping bases. Subsequent statewide polling, regional turnout patterns, and any late endorsements or campaign momentum could widen or close the gap among the top four before election day.
