The present work examines the constitution of the electorate by political parties in South Kivu in the DRC, where multipartyism appears as multi-tribalism. I focus on the mechanisms of persuasion and the strategies used by party structures and/or their candidates in electoral campaigns to secure the loyalty of "partisan" political predispositions and thus lead voters' inclinations to preference on the electoral market through propaganda stimuli (conjunctural force) combined with heavy variables. In this context, research into the nature of electoral participation and the behaviour of candidates in the structuring of popular support by competing parties in the same electoral district remains unanswered. This analysis is based on partisan functions to identify the type of conviction of candidates in the quest for the electorate, including their productions, in the first instance, and to highlight the degree of legitimacy and/or illegitimacy that is formed between mandates and their mandates in the second instance, along two axes. The restoration of the partisan landscape brings this work to a close.
