The PP would win the regional elections in Cantabria again, but the political scenario would be more complex than the one that emerged from the polls in 2023. A survey by Sigma Dos for El Mundo places the popular party as the leading force with 34.2% of the votes and between 14 and 15 seats, a similar figure to the current one but insufficient to govern alone.
The main novelty of the poll is not the position of the PP, which continues to clearly lead Cantabrian politics, but the decline of the Regionalist Party of Cantabria (PRC), which would lose two seats compared to the last elections and would cease to be the second parliamentary force. At the same time, Vox would consolidate its growth and increase its influence in the regional Chamber.
The survey was conducted between June 1 and 5 based on 995 interviews and depicts a more fragmented Parliament than the current one, with significant movements both within the center-right bloc and among regionalist and left-wing forces.
The PRC loses strength and the PSOE regains second position
The most striking data from the poll is the fall of the PRC. The regionalist party would go from the 20.8% of votes obtained in 2023 to 15.6%.
The loss of support for the PRC coincides with the political change that occurred after Miguel Ángel Revilla's departure from the front line. According to the survey, the current regionalist leader, Paula Fernández, remains a much less known figure than the historic Cantabrian leader.
Meanwhile, the PSOE would regain relative ground within the opposition bloc and overtake the PRC, becoming the second political force in Cantabria with 19% of the votes and between seven and eight deputies.
Vox continues to grow and strengthens its parliamentary role
The other major trend reflected in the poll is the advance of Vox. The party would go from 11.1% obtained in the 2023 regional elections to 14.4%, consolidating itself as the fourth political force and increasing its parliamentary representation.
The data published by El Mundo indicates that part of this growth comes from former popular voters, although it also incorporates support from the PSOE.
The result would be a representation of between five and six deputies, compared to the current four.
This growth is relevant because the PP would remain far from an absolute majority. Although the poll does not place Vox in a position to dispute the hegemony of the center-right space, it does reinforce its capacity to influence future parliamentary negotiations.
The situation partially recalls other regional scenarios where Vox has increased its presence without displacing the PP, but increasing its capacity to condition governability.
More fragmentation and emergence of new actors
Podemos-IU would slightly improve its results compared to 2023 and reach 5.3% of the votes. Although its growth is limited, it would allow it to maintain parliamentary presence.
For its part, Cantabristas is responsible for one of the most striking percentage increases in the survey. The formation would go from 1.7% to 4.2%, approaching the possibility of obtaining institutional representation.
This advance would occur mainly at the expense of the PRC and, to a lesser extent, the PSOE, reflecting greater competition within the Cantabrian regionalist space.
The poll thus points to a more atomized political scenario than the current one, with more parties competing for similar segments of the electorate.
What changes compared to the 2023 elections
The comparison with the results of the last regional elections clearly identifies the main movements of the Cantabrian electorate.
- PP: 35.8% → 34.2%.
- PSOE: 20.5% → 19.0%.
- PRC: 20.8% → 15.6%.
- Vox: 11.1% → 14.4%.
- Podemos-IU: 4.1% → 5.3%.
- Cantabristas: 1.7% → 4.2%.
The evolution shows that the three main parties lose support compared to 2023, although with very different intensities.
The PP retreats slightly, but maintains a wide lead over its rivals. The PSOE also loses ground, although it manages to position itself ahead of the PRC. The regionalists are the ones suffering the most pronounced fall in the survey.
In parallel, Vox continues to grow and Cantabristas gains visibility within the regionalist space.
With approximately one year to go until the next regional elections in Cantabria, the Sigma Dos poll depicts a more fragmented Cantabria, with a still dominant PP, a weakened PRC after the Revilla era, and an increasingly relevant Vox within the parliamentary balance.
