The Paraíba Senate race for first place remains tightly contested due to a fragmented field of over a dozen registered candidates following the close of filings in early August 2026. Nabor Wanderley holds a narrow edge in trader pricing amid his established municipal base in Patos and coalition support, while João Azevêdo (PSB), who stepped down as governor to run, and incumbent Veneziano Vital do Rêgo compete closely based on name recognition and prior polling leads. Other contenders including Rinaldo Júnior, Major Fábio, Marcelo Queiroga, and Rosilene Santana split remaining support across parties. Recent pre-campaign activity, coalition negotiations, and the absence of decisive statewide surveys have kept implied probabilities clustered, with separation likely hinging on turnout patterns, late endorsements, or regional mobilization in the final weeks before the October vote.
