Recent tensions over primary rules have kept the first-round outcome closely contested among social-democratic contenders. Raphaël Glucksmann and Olivier Faure have clashed publicly in early September over participation fees set at 15 euros and potential inclusion of additional figures such as François Ruffin, with Glucksmann insisting rules approved by militants must stand unchanged ahead of the October 9-10 electronic vote. This dispute, combined with a fragmented field that includes Jérôme Guedj, Philippe Brun, Emmanuel Maurel, and Ségolène Royal, has left trader consensus reflecting uncertainty about turnout among PS and Place publique sympathizers and the absence of a dominant polling leader. Scheduled debates and the September 15 candidate deadline could still shift positioning before first-round ballots close.
