Overview

• An IFOP‑Fiducial survey published September 29 places Raphaël Glucksmann at 14–16% among tested left candidates, ahead of Jean‑Luc Mélenchon at 12–13% and Fabien Roussel at 3–5%, with Édouard Philippe at 16–19% and the RN at 33–35%.
• The poll drew criticism from Mélenchon’s camp and Ecologists, including objections that Marine Tondelier was not tested in scenarios, even as Glucksmann’s team celebrated the momentum.
• Glucksmann refuses to enter a left primary that could include Mélenchon, arguing for a distinct social‑democratic offer and citing irreconcilable differences with LFI on foreign policy and democratic questions.
• Socialist leader Olivier Faure says Glucksmann is not the PS or broader left’s chosen contender, and Ecologist chief Marine Tondelier warns that framing a duel with Mélenchon risks aiding the RN.
• Despite rising visibility and a Place publique membership claim of about 12,000, Glucksmann’s institutional footprint remains small with two deputies and two senators as his movement gathers this weekend in La Réole.
