Quaest Poll to Gauge Rio de Janeiro State Race Ahead of First Round

A new Quaest poll will measure voting intentions for Rio de Janeiro's state government and Senate seats, with fieldwork from September 25-28 and release on September 29, less than a week before the first round of the 2026 elections. The survey covers 1,302 voters statewide with a 3-point margin of error. This is a routine pre-election poll, providing a snapshot of the race but no substantive change in the political landscape.
