Gracinha Caiado holds a commanding lead in trader pricing for first place in Goiás’s two-seat Senate race, reflecting her consistent position atop recent polling and strong name recognition tied to her role as former first lady and spouse of presidential candidate Ronaldo Caiado. A Real Time Big Data survey released September 22 showed her at 23% and Gustavo Gayer (PL) at 20% in combined first- and second-choice mentions, with the pair well ahead of Dr. Zacharias Calil (MDB) and Gustavo Mendanha (PRD). Gayer’s 21.5% market share aligns with his established federal deputy profile and PL base, while lower-priced candidates trail due to weaker polling trajectories and limited recent momentum. The October 4 vote, in which each elector selects two senators, continues to shape positioning as campaigns enter the final stretch.
