Recent polling from June and July 2026 shows a tight three-way contest for Piauí’s two Senate seats among Marcelo Castro (MDB), Ciro Nogueira (PP), and Júlio César (PSD), with Castro frequently leading first-preference votes while Júlio César and Ciro Nogueira trade positions in consolidated or second-vote scenarios. High rejection for Ciro Nogueira and the governing coalition’s backing for Castro and Júlio César have kept the second-place outcome fluid, as voters split preferences across the pair of vacancies. With the October election still weeks away and no major late shifts reported, traders assign comparable probabilities across the leading contenders for second place, reflecting uncertainty over final turnout, alliance consolidation, and undecided voters that could separate the pack.
