The race for first place in Sergipe's Senate contest stays tightly contested ahead of the October 4 vote, with recent polls showing Delegado André David holding a narrow lead or tie for top spot while André Moura, Rogério Carvalho, Delegado Alessandro, and Eduardo Amorim remain within striking distance. High shares of undecided voters and blank/null responses in surveys from August and early September have kept the field fragmented, limiting any single candidate's ability to pull away. Alliances tied to the concurrent gubernatorial race and the two-seat electoral system further complicate first-place dynamics, as voters select two names. No major late-breaking events have shifted the standings, leaving trader consensus on individual probabilities sensitive to final-week turnout and preference consolidation among the eleven registered candidates.
