The Amapá Senate race for second place remains tightly contested among the incumbents and mid-tier challengers because recent polling shows Rayssa Furlan commanding a clear lead for first while Randolfe Rodrigues and Lucas Barreto sit in a statistical dead heat for the remaining seat. Older surveys from late 2025 and mid-2026 placed Rayssa well ahead, with Randolfe edging Barreto in some head-to-head first-vote measures but the pair essentially tied when second preferences are included. Candidate registration closed recently with nine names on the ballot, yet no new statewide surveys have emerged since then, leaving traders to weigh name recognition, party machinery, and regional turnout patterns without fresh data. Developments such as October debate performances, last-minute alliances, or shifts in voter mobilization in Macapá and interior municipalities could quickly separate the field before the October 4 election.
