Marga Prohens would strengthen her political leadership in Baleares and would be one seat short of an absolute majority if the regional elections were held today. This is according to a survey conducted by IBES for Última Hora, which places the PP at 39.1% of the votes and 28 deputies, an improvement of three seats compared to the 2023 results.
The poll depicts a Parliament more tilted to the right than the current one. The sum of PP and Vox would reach 38 deputies, eight more than the 30 needed for an absolute majority and well above the progressive bloc.
The survey also confirms a trend already observed in other opinion polls published in recent months: the strength of the PP and Vox contrasts with the difficulties of the PSIB in mobilizing its electorate and with the persistent weakness of the space to the left of the socialists.
Prohens is one seat short of an absolute majority
The main conclusion of the poll is the strengthening of the Balearic PP. The party led by Marga Prohens would obtain 28 deputies, three more than in the 2023 regional elections, and would be two seats short of an absolute majority.
Podemos would be left out of Parliament, obtaining 3.2% of the votes. The sum of the center-right bloc would reach 38 deputies, compared to 21 for the left bloc. Although Prohens would still need Vox's support to ensure governability, the poll reflects a much stronger position than the one that emerged from the ballot boxes in 2023.
One of the most notable aspects of the poll is the difference between the vote loyalty of the right and the left. According to the vote transfer data published by Última Hora, the PP would retain 75.8% of its 2023 voters, while Vox would achieve a loyalty of 82.4%, the highest of all parties.
Furthermore, both parties manage to attract support from other political spaces.
The main vote transfers would be as follows:
• 13% of former El PI voters would now opt for the PP.
• 12% of PP voters would move to Vox.
• The PP would regain 5% of former Vox voters.
• Vox would attract 4.9% of former PSIB voters.
• Vox would receive 6.1% of former Podemos support.
On the other hand, the PSIB would retain only 58.6% of its voters and Podemos 58.4%. The socialists' main loss would not be to other parties, but to abstention and indecision.
PSIB falls to lows and Podemos continues without recovering
The poll depicts an especially complicated scenario for the Balearic left. The PSIB would lose four deputies compared to 2023 and would be left with 14 seats, with 22.8% of the votes. For its part, Podemos would disappear from the Parliament by not exceeding the minimum threshold necessary to obtain representation.
The poll confirms that the growth of Més per Mallorca and Més per Menorca would not compensate for the socialist setback and the disappearance of Podemos. The result would be an autonomous Chamber clearly more favorable to the conservative bloc.
