**Gustavo Gayer leads trader consensus for second place in Goiás’s October 4 Senate election, where voters select two senators.** Recent surveys, including Quaest (late August) and IGAPE (mid-September), show ex-first lady Gracinha Caiado (União) consistently ahead in consolidated first- and second-preference votes, while Gayer (PL) ranks second or within the margin for the remaining seat ahead of Vanderlan Cardoso (PSD), Dr. Zacharias Calil (MDB), and Gustavo Mendanha (PRD). High undecided shares above 25% and low spontaneous recognition persist, yet Gayer’s federal deputy incumbency, party backing, and stronger second-choice performance in Directa polling underpin the implied probability. No major late developments have altered this positioning in the past month, with the race remaining focused on turnout and name recognition among the 11 registered candidates.
