## Excerpt

With fieldwork overlapping in October, one poll puts the Socialists almost 12 points ahead and another puts the conservatives 6 ahead. Who ran each poll, which technical sheet we read and what is missing. The October 2026 barometer of the CIS, Spain's state-run Centre for Sociological Research (study 3582, fieldwork 1 to 6 October, 5,025 phone interviews, margin of error ±1.4%), estimates the Socialists (PSOE) at 34% and the conservative People's Party (PP) at 22.2%, an 11.8-point lead. Sigma Dos for El Mundo, IMOP for El Confidencial and Ateneo del Dato for elDiario.es, published between 19 and 25 October, put the PP first: 31.5% to 25.3%, 28.5% to 27.1% and 31.1% to 27.6%. Spain's electoral law requires every poll to come with, among other details, its sample size, margin of error and fieldwork dates, and bans publishing polls in the five days before the 29 November vote.
