Left-wing politicians launched the “Construire 2027” initiative on April 18, 2024 [2], calling for a common candidacy in the 2027 French presidential election.

The effort aims to prevent a split vote by uniting fragmented left-wing parties around a single majoritarian project. If successful, the coalition could present a unified front against center and right-wing opponents in the next electoral cycle.

Yannick Jadot, a senator of Europe Écologistes, is leading the movement alongside other figures including Raphaël Glucksmann and François Ruffin. The initiative has already garnered signatures from 45 elected officials and former ministers [1].

Events to promote the project have been held in Paris, including gatherings at the Bellevilloise venue in the 20th arrondissement. In a Franceinfo interview on May 18, 2024 [3], Jadot said the coalition has specific goals.

Despite the push for unity, internal contradictions remain regarding the method of selecting a candidate. The “Construire 2027” project mentions the possibility of organizing a primary to determine the nominee [1]. However, Raphaël Glucksmann expressed a "totally irrevocable refusal" to participate in a left-wing primary for the 2027 election [2].

Other figures within the movement have signaled a willingness to proceed even if consensus is not reached. François Ruffin said, "Nous irons à la présidentielle" — we will go to the presidential election — regardless of whether a primary fails [1].

Reports from L'Humanité suggest that the prospect of a primary is becoming stuck, which casts doubt on the coalition's ability to present a single unified candidate. The movement continues to struggle with balancing the ambitions of individual candidates against the strategic need for a single ticket.

“The initiative has already garnered signatures from 45 elected officials and former ministers.”

The formation of 'Construire 2027' represents a strategic attempt to replicate the 'union of the left' model to maximize electoral viability. However, the public disagreement between key figures like Glucksmann and the project's primary-based framework suggests that ideological and personal ambitions may still outweigh the pragmatic goal of unity, potentially leaving the left divided heading into 2027.
