Cyberattack Slows Social‑Democratic Primary as Glucksmann Leads

Overview

• The first round of the PS/Place publique/GRS primary opened as an all-electronic vote with about 140,000 registered participants and runs through Saturday at 20:00 with a second round set for 16–17 October if needed.
• Organisers said the platform was hit by a mass bot-driven attack shortly after voting began on Friday, forcing long queues to log in and reducing turnout to roughly 20,000 votes cast by 19:00 that night.
• The system used personalised identifiers and passwords sent by an independent provider, and organisers have notified the justice system and the national cyber‑security agency ANSSI while insisting recorded votes have not been compromised.
• Polls and coverage show Raphaël Glucksmann as the frontrunner, and the contest has exposed a sharp strategic split over whether to ally with Jean‑Luc Mélenchon’s La France insoumise that could determine post‑election legislative alignments.
• The disruption raises questions about the legitimacy and resilience of internet-only primaries, could depress participation for people with poor connections, and may affect the Socialist Party’s role in 2027 if turnout or the result weakens its standing.
