Overview
- The online first round opened Friday with roughly 140,000 people registered to choose one of five candidates: Raphaël Glucksmann, Olivier Faure, Ségolène Royal, Jérôme Guedj, and Emmanuel Maurel.
- Organisers say the voting platform was hit early by a bot-driven attack that generated massive fictitious connections, slowed access for many voters, and prompted them to seize the judiciary and notify ANSSI while insisting recorded votes remain intact.
- The most consequential contest is between Glucksmann and Faure as debates sharpened a strategic split over whether to keep the door open to alliances with La France insoumise, a divide that could determine coalition options for 2027.
- Officials reported lengthy queues and stalled voting periods that limited early turnout, and they set up assistance lines and local PS tablet points to help voters complete electronic ballots before Saturday evening's deadline.
- Because about 80,000 registrants are not formal party members, the electorate is unpredictable, the winner may not gain broad grassroots momentum like past primaries, and a runoff is scheduled for October 16–17 if no candidate wins an absolute majority.
