Rayssa Furlan maintains a commanding lead in Amapá’s Senate race for one of two seats, with late polls placing her at 25–30% of valid votes ahead of Randolfe Rodrigues, Lucas Barreto, and others. Her consistent edge stems from strong name recognition as a physician and former first lady, an active campaign emphasizing health and social issues, and alignment with her husband Dr. Furlan’s leading gubernatorial bid. Voting day on October 4 has narrowed opportunities for shifts, supporting the market’s assessment of her frontrunner status. Realistic challenges remain limited to unusually high turnout favoring rivals or last-minute undecided voter movement, though recent surveys show her margin stable within standard error ranges.
