CIS October Barometer: Socialists Open 11.8-Point Lead Over PP, 34.0% to 22.2%

Wednesday, October 14, 2026 · World · GSM News

Spain's state pollster, the Centre for Sociological Research (CIS), published its October barometer on October 14 with a striking result: the governing Socialist Party (PSOE) leads with 34.0% of estimated vote, ahead of the Popular Party (PP) at 22.2% and Vox at 17.1%, a gap of 11.8 points between the two main parties, up from 5.5 points in September. The study (No. 3582) is based on 5,025 telephone interviews carried out from October 1 to 6, with a margin of error of 1.4 points.

The socialists gained three points on September's barometer while the PP lost 3.3 points. Vox, at 17.1%, approaches its all-time high in the series. Sumar, under the Frente Amplio label, stands at 6.1% and Podemos at 3.1%.

The CIS raw vote intention is tighter: 25.3% for the PSOE against 14.7% for the PP.

The barometer was fielded before the snap election was called on October 5 and published in the middle of the campaign, where it has been received with scepticism by the opposition: private pollsters give the PP a clear lead, and the CIS, headed by a government appointee, has faced recurring criticism of bias. Its president maintains the centre applies the same method it has used for decades. (Source: Centre for Sociological Research (CIS), Spain)
