Methodology

Selection, update and ranking rules, and the limitations of Baromètre 2027.

Last updated: 19 July 2026

1. What Baromètre 2027 is

Baromètre 2027 is an independent aggregator. It collects, structures and presents public information about the 2027 French presidential election: polls, policies, news and videos. The Site conducts no polls, produces no opinion data and collects no visitors’ political opinions. It has no political affiliation and supports no candidate or party.

2. Polls

The voting-intention figures come from Wikipedia’s page listing polls for the 2027 French presidential election, published under the Creative Commons BY-SA licence. Figures remain the property of the polling organisations that produced them and are displayed for information with a link to the source.

For each polling wave—one organisation and one fieldwork period—if several candidate scenarios are published, the Site automatically selects the most complete scenario, meaning the one with the largest number of candidates. Polls are ordered from newest to oldest. Any second-round head-to-head match-ups are shown separately.

3. Candidates followed

The Site follows candidates who have officially declared that they are standing. They are presented from left to right across the political spectrum for readability, not as a value judgement. The list and ordering change as candidacies are declared or withdrawn.

4. News

The news feed is built automatically from the public RSS feeds of numerous French news outlets and supplemented by candidate-specific news searches. Articles are filtered using presidential-election keywords and sorted by date. Each item links to the original publisher; no article is republished in full.

5. Videos

The video section displays the latest publications from candidates’ and parties’ official channels, retrieved through their public feeds. Videos remain hosted on their original platforms and remain the property of their creators.

6. Data updates

Polls, news and videos are updated automatically several times a day. The date and time of the latest update are displayed on the relevant pages.

7. Limitations and warning

A poll is a snapshot of opinion at a given time and includes a margin of error defined by the polling organisation; it is not a forecast of the election result. The Site presents figures as published and applies no additional adjustment or weighting. For detailed methodology, including sample, collection method and adjustments, consult the polling organisation’s documentation.

The publisher seeks to keep information accurate and current but cannot guarantee this, particularly when original sources change or become unavailable.

8. Sources and corrections

Details of the sources used for polls, press and videos are available on the Sources page. To report an error or request removal, write to contact@elouardigroup.com.
