Once again, the French presidential election offers a strong surprise. If the National Front eliminates from the second round the conservative party (the Republicans), the voters have made emerge two movements constituted outside the traditional parties - En Marche! and La France insoumise, which put an end to the Socialist Party of François Mitterrand. Even before Emmanuel Macron came to power, everything indicates that public opinion will now judge the governments on their ability to make the revival of the European project the heart of a rapid social and territorial surge. Over the next few years, experiments will be carried out to meet this challenge regardless of the parliamentary majority.
