About 29N · What if…?

A scenario calculator: it converts the percentages of published polls into votes, from Spain as a whole down to each polling station, based on the official result of the Congress election of 23/07/2023 by polling station (Ministry of the Interior) and the electoral roll at 01/08/2026 (INE). It is a scenario, not a forecast or a poll of our own.

A private, independent service, unconnected with the Ministry of the Interior, the INE, the Electoral Board or any other official body, or with any polling company or media outlet.

Polls

For each poll, only its figures are shown, as facts, with its technical details and a link to the original publication; no third-party texts or charts are reproduced. From 24 to 28/11/2026 no polls are shown (article 69.7 of Organic Law 5/1985 on the General Electoral System). CIS data are reused with the credit “Origen de los datos: Centro de Investigaciones Sociológicas” (source of the data: Centre for Sociological Research).

Scenarios

The “What if…?” scenarios are assumptions applied to the chosen poll; they are not forecasts or polls of our own. Each one explains what is assumed and, when it is based on a published study (for example, the Centre d'Estudis d'Opinió barometer in the Aliança Catalana scenario), links to the source. Readers' proposals, if selected, are published without any details of the sender.

Use of the results
