Eduardo Braga (MDB), the incumbent senator, maintains a consistent lead in recent polling for first place in the Amazonas Senate contest, reflecting strong statewide support in both Manaus and the interior as voters select two candidates for the seats. Surveys from late September and early October, including those by Quaest, IPEN, Action, and DMP, place Braga at 27-38% in combined vote shares and 40% or higher as a first choice, ahead of Capitão Alberto Neto (PL) by double-digit margins in most first-preference measures. Neto, a federal deputy, holds second position at 17-21% overall and shows relative strength in the capital, while Wilson Lima and Plínio Valério trail in the race for the remaining spot. With the October 4 election imminent, these patterns in voter intentions underpin the current trader consensus on leading outcomes.
