Julio Cesar (PSD) secured a commanding lead for second place in the Piauí Senate race through a broad alliance with frontrunner Marcelo Castro (MDB) and backing from Governor Rafael Fonteles (PT), which consolidated voter support in the October 4, 2026, election. Recent polling, including AtlasIntel surveys, showed him pulling ahead of Ciro Nogueira (PP) in second-vote preferences, reflecting his long tenure as a federal deputy, local name recognition under the “Julim do Lula” banner, and emphasis on municipal strengthening and regional development. Official results with near-complete tallies confirmed his position at roughly 27% against Nogueira’s 24.7%, with limited remaining uncertainty tied only to final certification by electoral authorities.
