France: Who is Raphael Glucksman, the flag bearer of the left in the upcoming presidential elections?

Raphael Glucksman has a few months before the French presidential elections to consolidate his position after his victory in the primaries of the social democratic left. Between his defense of an alternative, social-democratic approach that supports the European project, and his deep disagreements with Jean-Luc Melenchon, leader of the radical left-wing "France Proud" party, Glucksman faces a challenge that goes beyond unifying the ranks of his camp, to include convincing broader segments of French voters.
