The first survey of 40dB after the summer leaves a demographic milestone: PP and Vox jointly exceed 50% of the estimated vote for the first time since the legislature began. PP would reach 32.4%, Vox 17.8%, PSOE 27.6%, Sumar 5.7% and Podemos 2.8%.
The fieldwork was carried out a month after the start of the Ceuta crisis, allowing for a comparison of the new snapshot with the last barometer prior to the summer, published in July.
The evolution is clear although not abrupt. PP and Vox rise. PSOE, Sumar and Podemos fall.
What changes since July: Vox +0.6, PP +0.4 and PSOE -0.4
Vox is the party that improves the most compared to the previous 40dB. It goes from 17.2% to 17.8%, an increase of six tenths. PP advances four, from 32% to 32.4%. PSOE travels exactly that distance in the opposite direction: it falls from 28% to 27.6%. Sumar goes from 5.8% to 5.7%, one tenth less, while Podemos declines from 3.1% to 2.8%, three tenths.
For its part, SALF rises slightly, from 2.1% to 2.2%.
The comparison thus leaves a very clear signal:
- PP: +0.4
- PSOE: -0.4
- Vox: +0.6
- Sumar: -0.1
- Podemos: -0.3
PP and Vox go from 49.2% to 50.2%
In July, PP and Vox totaled 49.2%. Now they reach 50.2%. They gain a joint point and cross for the first time the 50% threshold in the 40dB series during this legislature.
The opposite movement occurs on the left. PSOE, Sumar and Podemos totaled 36.9% in July. Now they remain at 36.1%.
The distance between the two blocks therefore goes from 12.3 points to 14.1 points. The gap increases by 1.8 points since July.
If SALF is included, the right reaches 52.4%
Vox is the party that gains the most after the summer
The most favorable monthly movement corresponds to Santiago Abascal. Vox gains six tenths and reaches 17.8%. Moreover, it is the only one of the three major parties that is clearly above its result in the general elections of 2023. Then it obtained 12.4% and now adds 5.4 points more.
PP, despite being the leading force, is still seven tenths below the result of 23J. PSOE is 4.1 points below.
The accumulated transformation during the legislature consists not so much of an extraordinary expansion of PP as of the growth of Vox and the socialist loss.
PP returns to 32.4%, but remains below 23J
PP reaches 32.4%. It is four tenths more than in July and matches its best record of 2026 in this series. But it remains below the 33.1% achieved in the general elections of 2023.
This introduces an important reading for Feijóo: the possibility of reaching La Moncloa does not depend on whether the PP has experienced a great electoral expansion. It mainly depends on Vox being five points above 2023 and on the left block having weakened.
The PSOE loses four tenths and is 4.8 points behind the PP
The PSOE drops to 27.6%. In July it was at 28%. The loss is moderate, four tenths, but coincides with the popular advance and causes the PP-PSOE distance to increase by eight tenths at once.
Feijóo goes from leading Sánchez by four points to leading him by 4.8.
The alternative left also does not capture the socialist fall
One of the problems for Sánchez is that the vote lost by the PSOE does not turn into a recovery for its possible partners. Sumar slightly drops to 5.7%. Podemos also retreats to 2.8%. Together they only reach 8.5%.
In the 2023 elections, they ran under the same candidacy and achieved 12.3%. The space is now 3.8 points below that joint result.
The weakness of Sumar and Podemos is decisive for any future investiture majority, because even if the PSOE resisted around 28%, it would need a much stronger alternative left to compensate for a PP-Vox sum greater than 50%.
Ceuta enters the survey with immigration at the center
The timing of the fieldwork matters. The interviews were conducted approximately a month after the start of the Ceuta crisis.
This means that we are not facing an immediate reaction from the first hours. There has been time for the migratory issue, the relationship with Morocco, border security, and the Government's response to be incorporated into political perceptions.
The survey ended, however, before some subsequent events, including new revelations from the police report on Ceuta and Sánchez's appearance in Congress.
For this reason, it cannot be considered a snapshot of the full effect of all the news known during the first days of September.
Vox appears as the party most capable of managing immigration
Here probably appears the data that best connects the Ceuta crisis with the rise of Vox. When 40dB asks which party is best equipped to manage immigration, Vox takes the first position.
27% of all Spaniards point to Abascal's party. The PSOE appears second, with 18.4%. The PP stands at 13.9%.
Furthermore, 23% respond that none of them are qualified.
Even one in four voters of the PP prefers Vox to manage immigration. The penetration of Vox in the popular electorate is especially striking. Among those who would currently vote for the PP, 56% consider their own party to be the most capable of managing immigration. But 23% point to Vox.
Among Vox voters, on the other hand, support for their own party is almost monolithic: 89% consider it the most qualified.
Vox has the highest electoral loyalty
The strength of Vox is also evident in its ability to retain voters. 85.9% of those who voted for Abascal in 2023 say they will do so again.
- In the PP, loyalty is 77.5%.
- In the PSOE, it is 68.4%.
- And in Sumar it drops to 44.5%.
Vox therefore has not only an expanding base but also the most stable base among the major parties.
Almost 13% of PP voters are moving to Vox
The transfer between PP and Vox is clearly tilted towards Abascal. 12.8% of those who voted for the PP in 2023 now say they would support Vox. In the opposite direction, only 3.4% of former Vox voters would move to the PP. The ratio is practically four to one.
The PSOE loses more votes to the right than to the left
The transfer matrix leaves another important data.
Among socialist voters of 23J:
- 6.8% would go to the PP.
- 4.3% to Vox.
- 3.9% to Sumar.
- 1.5% to Podemos.
That is, the leaks to PP and Vox total 11.1%, clearly more than those directed towards Sumar and Podemos. Furthermore, 7.5% of former socialist voters remain undecided.
Vox also leads mobilization
71.6% of those who voted for Vox in 2023 assure that they will vote with total certainty. It is the highest percentage among the four main electorates.
Sumar stands at 69.2%, PP at 68.5%, and PSOE at 66.3%.
Vox thus combines three simultaneous advantages: growth compared to 2023, maximum loyalty, and high mobilization.
Vox leads among those under 35
Generational segmentation adds another structural change. In direct voting intention, Vox appears as the leading force among citizens up to 34 years old. Its support decreases as age increases.
The PSOE, on the contrary, finds its main strength in the older electorate: among those over 65 years old, it hovers around 30% of direct voting intention.
Result of 40dB and comparison with July and 23J
The first 40dB barometer after the summer places PP and Vox above 50% combined for the first time during the legislature. Vox is the party that grows the most compared to July, while PSOE, Sumar, and Podemos decline.
| Party | September | July | Change | 23J | Change vs. 23J |
|---|---|---|---|---|---|
| PP | 32.4% | 32.0% | +0.4 | 33.1% | -0.7 |
| PSOE | 27.6% | 28.0% | -0.4 | 31.7% | -4.1 |
| Vox | 17.8% | 17.2% | +0.6 | 12.4% | +5.4 |
| Sumar | 5.7% | 5.8% | -0.1 | 12.3%* | — |
| Podemos | 2.8% | 3.1% | -0.3 | Integrated in Sumar | — |
* Podemos ran integrated in Sumar in the general elections of 2023. Together, Sumar and Podemos now total 8.5%, compared to the 12.3% obtained by the unitary candidacy of 23J.
