The Amapá Senate race for first place remains wide open because voters select two senators and recent polling shows a fragmented field with no dominant frontrunner. Incumbents Lucas Barreto and Randolfe Rodrigues hold established bases, while Rayssa Furlan has posted the highest single-candidate support in the latest survey amid her alignment with a leading gubernatorial ticket. Other contenders including Alliny Serrão, Acácio Favacho, and Capi draw measurable backing from distinct regional and party coalitions. The official campaign launch on August 16 has not yet produced decisive shifts, leaving room for last-minute alliances, turnout variations across municipalities, and dual-vote strategies to reorder the top finishers before October.
