The Paraná Senate race for two seats remains highly fragmented ahead of the October vote, with recent party conventions confirming a broad field including Alexandre Curi (Republicanos), Deltan Dallagnol (Novo), Gleisi Hoffmann and Dr. Rosinha (PT), Filipe Barros (PL), and Cristina Graeml (PSD). July polls from Quaest and Paraná Pesquisas showed no dominant leader, with Álvaro Dias (MDB) ahead in some scenarios but absent from others, leaving the remaining contenders statistically tied within margins of error. Deltan Dallagnol’s eligibility challenge before the Electoral Justice has added procedural uncertainty without yet shifting voter intentions. Traders assign roughly equal 44-50% implied probabilities across most listed names because the multi-candidate structure, limited name recognition for several aspirants, and absence of decisive late polling or endorsements keep first-place outcomes wide open. A strong debate performance, major endorsement, or favorable court ruling on eligibility could consolidate support and create separation before election day.
