Résumé
This article assesses the social and political motivations for mobilization during the French “Right and Centre” primary election of November 2016 through an exit-poll administered in seven departments of metropolitan France. Beyond the requirement that voters pay a fee to participate in this election, our survey emphasises the diversity of voters’ motivations. Whereas some of them mobilized because of their proximity to the main right-wing party (“Les Républicains”) and its networks, others went to vote mainly owing to their social characteristics. The landslide victory of François Fillon in this election can be interpreted as a twofold ability to meet the expectations of this part of the right-wing electorate and to use local partisan networks.
