**Recent polling in the Piauí Senate race, which elects two senators on October 4, 2026, shows a tight three-way contest among Marcelo Castro (MDB, incumbent), Ciro Nogueira (PP, incumbent), and Júlio César (PSD, federal deputy).** Latest Datafolha data from mid-September places the top trio within the margin of error at 15–17% each in stimulated totals for the dual vacancies. Castro and Nogueira often lead first-preference scenarios, while Júlio César performs strongly in second-vote breakdowns and benefits from alignment with the state government base. Elevated rejection of Nogueira (noted across earlier surveys) caps his expansion, leaving room for Júlio César to consolidate support as the likely second-place finisher. High undecided and blank/null shares, plus the mechanics of voters selecting two names, sustain volatility and keep separation among contenders narrow.
