What is at stake in Cantabria on 23 May 2027
Cantabria is one of Spain's 17 autonomous communities, with its own parliament and government. Voters elect the 35 members of the Parliament of Cantabria (Parlamento de Cantabria) from party lists, on the same day as municipal elections across Spain; the chamber then elects the regional president. An absolute majority is 18 seats; short of that, a party needs allies or abstentions to win the investiture vote. The current president is María José Sáenz de Buruaga (PP). Main candidates: María José Sáenz de Buruaga (PP), Paula Fernández Viaña (PRC), Pedro Casares (PSOE) and Leticia Díaz (Vox).
The parties in the polls:
- People's Party (PP): Spain's main centre-right party.
- Socialist Party (PSOE): Spain's main centre-left party.
- Regionalist Party of Cantabria (PRC): the Cantabrian regionalist party long led by Miguel Ángel Revilla.
- Vox: the national hard-right party.
- Podemos: a left-wing party born from the 2011 anti-austerity protests.
- Cantabristas: a left-wing Cantabrian nationalist party.
In the 2023 election, on a turnout of 65.3%, PP won 35.8% (15 seats), PRC won 20.8% (8 seats), PSOE won 20.6% (8 seats) and Vox won 11.1% (4 seats). In 2023 Podemos ran in coalition with other left-wing groups in several regions; the figure is for that list.

How we calculate
- Average: each pollster's latest poll with fieldwork ending in the 90 days before the newest Cantabria poll; a simple average by party. Few regional polls are published, so the window counts back from the newest poll, not from today. Where there is only one, we show that poll and label it “one poll only”.
- Polls commissioned by a party, and polls that only publish seats, are left out of the average. The seats shown are those of the newest poll that publishes them; Sondagio does not calculate its own seat allocation.
- Spanish electoral law (LOREG, art. 69.7) bans publishing polls in Spain in the five days before the vote (18 to 22 May 2027). During that period the figures are frozen.
- Data: every published poll, compiled on Wikipedia (CC BY-SA 4.0); the 2023 results come from the same table. Each row links to the original publication. Party colours are indicative.
- Independence: Sondagio's founder has no ties to any candidate or campaign. The averages are calculated by formula from every published poll; no figures are adjusted by hand.
