The emergence of the People’s Primary and the Taubira Collective is a good opportunity to study the ways in which digital tools can enable emerging political movements to become competitive actors in party struggles. Tweets were collected from left party/campaign accounts (@Taubirapour2022 for the Taubira Collective, @EELV for the Green Party, @partisocialiste for the Socialist Party, @Melenchon_2022 for France Unbowed) from 1 January to 1 March 2022 and accounts promoting primaries (@PrimairePop for the People’s Primary, @lesRépublicains for the Republican primary, @EELV for the Green primary) from 2 weeks before each vote to 2 weeks after, using Minet, a web mining tool developed by Sciences Po researchers.
