In the Amapá Senate race, where voters select two candidates for the state's two seats on October 4, recent polling shows Rayssa Furlan holding a clear lead for first place while Randolfe Rodrigues and Lucas Barreto remain closely matched for second. Multiple surveys from August and early September place Barreto and Randolfe within the margin of error behind Furlan, with support split among their respective PSD and PT coalitions plus scattered backing for Alliny Serrão and Acácio Favacho. The market's near-even pricing on the second-place outcome reflects this stable deadlock, sustained by limited late shifts in voter preferences, comparable name recognition among incumbents, and the absence of major campaign events or endorsements that have altered the balance in recent weeks.
