They want to advance in a close march towards 2027. The united left, which is defending a joint candidacy for the presidential election, met on Saturday November 15 in a significant show of unity against the right. They have done it “oath”Last July in Bagneux (Hauts-de-Seine), to hold a “general candidate” for 2027: PS boss Olivier Faure, chief Ecologist Marine Tondelier, former LFI deputies Clémentine Autain (L’après) and François Ruffin (Debout!) and Génération.s coordinator Benjamin Lucas meet at Trappes (Yvelines).

The leftist thinker of unity in 2024, Lucie Castets, is also present to provide a more concrete aspect to this hitherto unseen promise. The introduction will take place at “fall 2026”he announced, stating that the exact date and method of this appointment process will be announced in the first half of December. “When we give the date, it creates a ripple effect, dynamic”said Lucie Castets, based on an Elabe survey for BFMTV which confirmed that 72% of New Popular Front voters wanted a candidate from the left.

“This is the most difficult political fight we have ever faced”convinced Marine Tondelier, the spearhead of this union and was declared a candidate. But the two left-wing candidates who are best placed in the polls, LFI leader Jean-Luc Mélenchon and Place publique leader Raphaël Glucksmann, with two antagonistic lines, refuse any participation in this process, believing that they are able to impose themselves by realizing a useful vote. The PCF also at this stage does not want to be part of any desire for unity. But “they have an anti-fascist culture and a tradition of unity”notes Clémentine Autain.
