The Paraíba Senate race remains highly competitive with no dominant frontrunner as multiple candidates hold comparable support heading into the October election. João Azevêdo’s resignation from the governorship to run on the PSB ticket, combined with PT backing for both him and MDB’s Veneziano Vital do Rêgo, has fragmented the center-left vote while REP’s Nabor Wanderley and PL’s Marcelo Queiroga consolidate other blocs. Recent candidate conventions and coalition announcements in early August have clarified the field without producing decisive leads, leaving trader probabilities clustered tightly around the top names. Late-campaign shifts in local alliances, turnout in key municipalities, or national endorsements could quickly reorder the standings before ballots are cast.
