As soon as the polls closed for these Castilla y León elections of March 15, at 8 p.m., the various exit polls began to be published, making a first estimate of the results that will be officially known in a few hours.
Demócrata compiles all surveys published so far.
The Cortes of Castilla y León will be composed of 82 procurators, one more than in the previous legislature. The absolute majority stands at 42 seats.
The provincial distribution -15 in Valladolid, 13 in León, 11 in Burgos, 10 in Salamanca, 7 in Ávila, Palencia, Segovia and Zamora, and 5 in Soria- turns each constituency into a decisive micro-scenario.
What the previous surveys said
The polls published before the elections by different polling institutes agreed on one point: the Popular Party would win the elections, although it would still need the support of Vox to govern. The most recent ones placed the PP around 30-34% of the vote, while they gave the PSOE close to 28-30% and Vox nearing or exceeding 20% of the votes.

Average of polls

- The PP remains as the first force
- The PSOE resists as the second party
- Vox is the one that grows the most in the campaign
What is at stake in the Castilla y León elections
The elections of March 15 are the third major regional appointment of the 2026 political cycle after the elections in Extremadura and Aragon.
The result will mark three political keys:
- If the PP manages to govern with less dependence on Vox and increases in votes compared to 2022
- If Vox consolidates its electoral growth and manages to break 20%, for the first time in regional elections
- If the PSOE manages to stop its fall in the autonomous cycle, maintaining its results from the previous elections
The electoral campaign began on February 27 and concluded on March 13. The constitutive session of the Cortes will take place on April 14.
