Notes

Sigma Dos for El Mundo. Mixed CATI/CAWI via Panel Sigma Dos by Trust Survey; eligible voters aged 18+ residing in Spain. Publication date follows the pollster’s original release (2 November), rather than secondary aggregators. Source labels preserved: Frente Amplio and Front Valencià are distinct from Sumar and Compromís. Only explicitly reported vote shares are entered; omitted parties are not zero.
