Raphaël Glucksmann opens French presidential campaign with left unity unresolved

Raphaël Glucksmann launched his campaign for France’s 2027 presidential election on Monday, 12 October, saying the battle to revive the divided left had begun. His declaration followed a first-round victory in a social-democratic primary. The result established his candidacy within that political family, while the question of a wider left alliance remains unsettled.

Glucksmann, 46, is co-president of Place publique. He won about 66% of the vote in Sunday’s primary, according to Le Monde. LCP reported that the result made him the officially designated presidential candidate of the social-democratic family. His competitors were Olivier Faure, Ségolène Royal, Emmanuel Maurel and Jérôme Guedj.

In his victory speech, Glucksmann described himself as a candidate for social and fiscal justice, ecological change and democracy. He presented his campaign as a break with President Emmanuel Macron’s politics and with Jean-Luc Mélenchon’s dominance of the left, while identifying the far right as his main adversary, Le Monde reported. LCP quoted him declaring: ‘The battle of France begins.’

What Glucksmann’s primary victory establishes

Glucksmann received approximately 79,000 votes, according to Le Monde. Faure received about 17,400, or 14%, the newspaper reported. The first-round result settled the primary contest and designated Glucksmann as the social-democratic candidate. It did not decide how parties outside the primary would approach the presidential race.

Putting the campaign into operation is another immediate task. Le Monde reported that arrangements for campaign resources had not yet been made after the primary. Glucksmann wanted prompt access to about €1 million in voter contributions, the newspaper said, after roughly €250,000 in primary costs. Those figures describe the resources at issue at that point; the arrangements had yet to be made.

Why a broader French left alliance remains uncertain

Glucksmann has ruled out an alliance with Mélenchon’s La France insoumise, or LFI, in legislative elections expected after the presidential vote in April 2027, Le Monde reported. Cooperation with LFI divided the primary campaign. Green senator Yannick Jadot, a Glucksmann supporter, told the newspaper he considered the alliance question settled. Others on the left have challenged that position.

Marine Tondelier, the Greens’ leader, called Glucksmann’s refusal of a broad left and Green alliance a ‘choice of retreat’, LCP reported. She argued that winning required an end to factionalism and to treating parts of the left as irreconcilable. Her response shows the distance between support from Glucksmann’s primary rivals and agreement across the wider left.

There is also a practical question about who controls local alliances. Le Monde reported that some Socialist members favor unity with LFI and that party decisions in the 2024 snap elections and 2026 municipal elections allowed cooperation in some places. The Socialists joined the Nouveau Front Populaire alliance with LFI in 2024 without consulting Glucksmann, the newspaper reported. Socialist secretary-general Pierre Jouvet said local agreements remained possible.

The Greens have their own decision ahead. Le Monde reported that they were due to determine their strategy on 13 December, with some members favoring an independent presidential candidacy. Until those choices are made, Glucksmann’s primary win establishes his candidacy within the social-democratic family, while the membership and terms of any broader coalition remain open.

What the polling says before his designation

Surveys cited by LCP on Monday were conducted before Glucksmann won the primary. A Harris Interactive survey taken from 5 to 8 October put him at 10% to 11% in tested scenarios, against 18% to 19% for Mélenchon. LCP reported that no poll in its account yet reflected Glucksmann’s official designation, so those numbers cannot show whether the result changed voters’ preferences.

Earlier polls also varied with the candidates tested. LCP reported that an Ifop-Fiducial survey from 25 to 29 September put Glucksmann at 11% with Édouard Philippe as the central-bloc candidate. An Ipsos BVA survey from 3 to 9 September put him at 12.5% or 13.5%, depending on the central-bloc scenario. The figures describe different hypothetical contests before the primary.

The campaign now faces decisions about its organization and its relationships with other parties. In a France 24 interview about the launch, Paris Panthéon-Sorbonne political scientist Damien Lecomte warned that Glucksmann should avoid being seen as ‘the new Macron’, which he said would not be a winning message. The Greens’ pending strategy decision and the unresolved Socialist and LFI alliance question leave the reach of Glucksmann’s appeal open.
