The possibility of early general elections finds the PP clearly ahead of the PSOE and the sum of Alberto Núñez Feijóo and Santiago Abascal installed well above the absolute majority, but the latest survey from SocioMétrica for El Español introduces an important nuance regarding the snapshot from just a week ago: the advantage of the PP-Vox bloc remains enormous, although it slightly decreases in seats.
The new survey attributes to the PP 33.4% of the votes and 143 deputies. The PSOE would obtain 26.5% and 106 representatives, while Vox would reach 18.1% and 62. The new Broad Front being prepared in the Sumar space would be at 5.3% and six deputies, and Podemos would retain two representatives.
PP and Vox would jointly sum 205 seats. With the UPN deputy, the figure would rise to 206, thirty above the 176 that mark the absolute majority of Congress.
The comparison with the previous SocioMétrica is especially useful because it was published on September 27, just a week earlier. That measurement placed the PP at 33.9% and 145 seats, the PSOE at 25.7% and 107, Vox at 18% and 62, Sumar at 5.7% and five, and Podemos at 3.3% and two.
PP loses two seats, PSOE one, and Vox remains
The comparison between the last two measurements of SocioMétrica leaves a much more stable picture than what the political climate of recent days might suggest.
The PP drops from 33.9% to 33.4%, half a point less, and goes from 145 to 143 deputies. It loses two representatives.
The PSOE makes exactly the opposite movement in percentage, but not in seats. The socialists rise from 25.7% to 26.5%, eight tenths, although their parliamentary projection slightly decreases from 107 to 106 deputies.
Vox practically does not move. It goes from 18% to 18.1% and maintains its 62 seats.
The Sumar space does change configuration. The previous survey gave it 5.7% and five deputies. The new estimate now measures a hypothetical Broad Front, which would obtain 5.3% and six representatives. The comparison must be made with caution because it is not exactly the same electoral offer.
Podemos maintains two deputies.
The conclusion, therefore, is that in a week there is no upheaval occurring. The PSOE improves in percentage, but does not convert that recovery into more seats; the PP slightly retreats and Vox remains stuck at 62.
PP and Vox drop from 207 to 205 seats compared to the previous survey
The effect is also noticeable in the sum of the right.
In the SocioMétrica of September 27, PP and Vox gathered 207 deputies: 145 from PP and 62 from Vox.
Now they would sum 205: 143 and 62.
They lose, therefore, two joint seats compared to a week ago.
This does not compromise the absolute majority at all, because they would still have 29 more deputies than necessary. If UPN joins, they would reach 206.
The photograph is relevant in light of a possible advance: the PP-Vox majority continues to be very wide, but the new poll does not widen it, rather it slightly reduces it compared to the previous SocioMétrica.
PSOE recovers eight tenths, but loses one deputy
One of the most curious data from the survey shows again that percentage of vote and number of seats do not necessarily evolve in parallel.
PSOE gains eight tenths in just one week: it goes from 25.7% to 26.5%. However, it drops from 107 to 106 representatives.
The explanation lies in the provincial distribution of the vote. In Spanish general elections, it is not enough to sum national percentage; what is decisive is how that vote is distributed among the 52 constituencies and who gets the last deputy in each one.
This means that Sánchez improves compared to the last survey in estimated support, but not in parliamentary representation.
The distance between PP and PSOE reduces from 8.2 to 6.9 points
The advantage between the two major parties also narrows.
A week ago, SocioMétrica placed PP at 33.9% and PSOE at 25.7%. The distance was 8.2 points. Now Feijóo obtains 33.4% and Sánchez 26.5%.
The difference drops to 6.9 points. In just one week, it reduces, therefore, by 1.3 points. The movement comes from both sides: PP gives up half a point and PSOE recovers eight tenths.
Even so, the parliamentary distance remains wide: 143 seats compared to 106, a difference of 37 deputies.
Vox remains at 62 seats and continues to almost double the 23J
Vox is the most stable formation compared to the previous survey.
It goes from 18% to 18.1%, barely one tenth more, and retains exactly 62 deputies.
The really relevant comparison for Abascal is in the 23J. Vox then obtained 33 deputies and approximately 12.4% of the votes. The official results were published by the Central Electoral Board.
The new estimate places it at 62. In votes, it goes from 12.4% to 18.1%, a gain close to 5.7 points.
Vox would thus practically double its current representation.
Against the 23J, PP gains six seats
The PP obtained 137 deputies in the last general elections. SocioMétrica now attributes it 143. The improvement would be six seats.
In percentage, the change is much smaller. The PP obtained approximately 33.1% in 2023 and would now reach 33.4%, just three tenths more. Again, the bulk of the parliamentary growth of the right-wing bloc does not come from the PP, it comes from Vox. PP and Vox go from 170 to 205 deputies.
This is probably the most powerful comparison with the general elections of 2023.
PP and Vox jointly obtained 170 deputies on 23J: 137 and 33. Now they would achieve 205.
That is 35 more seats. The PP contributes six of that gain. Vox, 29.
The alternative majority would therefore be much larger than in 2023, but it would also be much more balanced between the two parties.
Vox would go from contributing less than one in five deputies of that sum to approximately three in ten.
The PSOE loses 15 deputies since the last general elections
The socialist evolution is the reverse.
The PSOE obtained 121 deputies on 23J, adding its corresponding territorial candidacies. SocioMétrica now places it at 106. That is 15 deputies less.
In percentage of votes, the drop is greater: it goes from 31.7% to 26.5%, a little over five points.
The recovery of eight tenths recorded compared to the previous SocioMétrica does not compensate, therefore, for the accumulated deterioration during the legislature.
Sánchez would be better than a week ago in percentage, but still far from the result with which he managed to stay in La Moncloa in 2023.
The left to the left of the PSOE loses a large part of its representation
The comparison of the new Frente Amplio with 2023 requires special care because the electoral offer has changed.
On 23J, Sumar ran as a joint candidacy that included Podemos and obtained 31 deputies.
SocioMétrica now projects six deputies for the Frente Amplio and two for Podemos. Together they would be eight.
Against the 31 of 2023, the space would lose 23 representatives.
This is not a perfect comparison between acronyms, but it does allow measuring the total representation of the political space situated to the left of the PSOE.
PSOE, Frente Amplio, and Podemos would sum 114 deputies
If the three main state leftist forces appearing in the new poll are added, the result would be:
PSOE: 106.
Frente Amplio: 6.
Podemos: 2.
Total: 114 deputies.
In 2023, PSOE and Sumar, with Podemos integrated, jointly reached 152 representatives: 121 and 31. The difference would be 38 seats.
The investiture majority would not be reconstructed either
According to the territorial estimate published alongside the survey, even incorporating ERC, Junts, EH Bildu, PNV, BNG, and the rest of the forces that facilitated Sánchez's investiture in 2023, the block would be far from the 176 deputies.
The published estimate places that sum around 143 seats.
PSOE retains only 64.2% of its voters from 23J
The transfer matrix again shows one of the main problems of PSOE.
Only 64.2% of those who voted for Sánchez in 2023 say they would repeat now. SocioMétrica estimates that about 369,000 former socialist voters would choose the PP. Another 274,000 would shift towards Vox. And approximately 690,000 remain undecided.
This last group is probably the main margin for socialist recovery in the event of a campaign: they are not voters who have necessarily switched to another party, but former voters who have not yet decided what to do.
PP and Vox retain more than eight out of ten voters
Fidelity is significantly higher on the right. The PP retains 84% of those who voted for it in 2023. Vox, 83.5%.
Moreover, both parties manage to mobilize a relevant part of those who abstained in the last general elections.
According to SocioMétrica, 12.2% of the abstainers from 2023 would now vote for the PP. 10.8% would choose Vox. PSOE would capture 9.2%.
This mobilization differential helps to understand why PP and Vox can notably expand their representation compared to 23J without the PP having experienced significant percentage growth.
Madrid reflects the new balance between the three major parties
The territorial projection also leaves some significant data.
In the Community of Madrid, the PP would retain 17 deputies.
PSOE would drop to nine.
Vox would reach eight, three more than in the 2023 general elections.
The new Broad Front would obtain three and Podemos one.
The result would leave Vox just one deputy behind PSOE in one of the largest constituencies in the country.
Catalonia remains the main socialist counterweight
In Catalonia, the PSC would continue to be the leading force with 18 deputies, one less than in 2023.
ERC would rise to eight.
The PP would also reach eight, two more than in the last general elections.
Vox would achieve six, four more.
Junts would drop to five.
Podemos would obtain one.
Catalonia would thus remain one of the territories where the PSOE retains the greatest advantage over the right, although PP and especially Vox would substantially improve compared to the 23J.
The PSOE would retreat in a good part of the map
The projection of SocioMétrica attributes socialist losses compared to the 23J in numerous communities.
- The largest would be Castilla y León, where it would lose three deputies.
- In Andalusia, it would cede two.
- And it would lose one in Balearic Islands, Canary Islands, Cantabria, Castilla-La Mancha, Catalonia, Extremadura, Galicia, La Rioja, Madrid, Murcia, and Basque Country.
The loss is not concentrated, therefore, in a single territory.
Vox concentrates its greatest gains in Andalusia and Catalonia
Vox presents the opposite movement in Spain
Its greatest advance would occur in Andalusia, where it would gain six deputies compared to 2023.
In Catalonia, it would add four.
In Valencia Community, Castilla y León, Castilla-La Mancha, and Madrid, it would gain another three in each territory.
This territorial distribution explains why a national increase of around six points can translate into 29 additional deputies.

SocioMétrica Survey: current result, previous survey, and comparison with the 23J
The express survey of SocioMétrica maintains a wide majority of PP and Vox, although both go from 207 to 205 seats compared to the survey published a week earlier. Against the 23J, the sum of PP and Vox gains 35 deputies, while the PSOE would lose 15.
