The Center for Sociological Research (CIS) plans to publish this Thursday its opinion barometer for the month of April, the first made after the presentation of the Sumar platform and the candidacy for the general elections of the second vice president of the Government, Yolanda Díaz, the accusation of “manipulation” of the March survey launched by Podemos against the president of the polling institute, José Félix Tezanos, and after the failed vote of no confidence by Vox, led by Ramón Tamames.

The new CIS study is based on interviews carried out during the first two weeks of April, a month that began with the debut of Sumar, which took place on the 2nd. It was an act that was attended by no representative of the leadership of Podemos and that it was held in the midst of tensions between the purples and those related to the vice president on account of the integration of Podemos in this new space to the left of the PSOE.

In addition, April is the first barometer after the formation led by Ione Belarra complained that, in the March study, the CIS did not count for Unidas Podemos the responses of the people who announced their vote for Sumar.

From Podemos they maintain that March was the first barometer in which the support for Sumar was included in the category of ‘other parties’ and they attribute the drop in the percentage of votes that that survey gave them to this change.

For this reason, the purples charged Tezanos, accusing him of “manipulation” and “partisan” use of the CIS and complained that the drop in their estimate was linked to the controversy generated around the reform of the law known as the ‘only Yes is yes’.

Specifically, in that Unidas Podemos survey, it lost third place in favor of Vox, for the first time since last summer. The study gave the confederal space a support of 10%, 2.7 points less than the previous month and 4.2 points below its data for the month of January. It was his third consecutive fall in the barometers and he was 2.8 points below his result in the last generals.

The study that is published this Thursday is also the first after the motion of censure that Vox presented against President Pedro Sánchez with the economist Ramón Tamames as a candidate, an appointment in which the Government divided its intervention between Sánchez himself and Yolanda Díaz.

In the March barometer, the PSOE rose six tenths compared to the previous one and achieved a support of 32.7%, its highest level of the legislature in the CIS polls (which it had already reached in October and November 2022). That percentage was 4.7 points higher than the 28% with which the Socialists won the last general elections.

This rise and the setback that the CIS attributed to the PP placed the advantage of the PSOE over the ‘popular’ at 4.7 points. Specifically, those of Alberto Núñez Feijóo were calculated to drop almost two points, up to 28%, a percentage in any case 8 points above the support that Pablo Casado achieved in 2019.

On its side, the fall of United We Can left Vox as the third party with the highest vote estimate, despite the fact that those of Santiago Abascal returned to the usual range of recent months, with support of 10.1%, compared to 15% that added in the last generals.
