The fragmented field and elevated undecided voters have kept the race for second place in Sergipe’s two-seat Senate contest tightly bunched, with trader prices reflecting that uncertainty. Recent surveys, including an SM Pesquisas poll from mid-September, show Delegado André David ahead but followed closely by André Moura, Edvaldo Nogueira, Rogério Carvalho, and others in the single digits to low teens, while spontaneous responses remain dominated by “none” or blank. Because each elector casts two votes and the campaign enters its final weeks before the October 4 ballot, modest shifts in turnout or late consolidation among the main coalitions could reorder the lower half of the top tier. High numbers of still-undecided respondents and the absence of a clear second-place frontrunner sustain the narrow spreads across the leading contenders.
