The comparative literature has devoted considerable attention to why individuals join political parties. This is especially important in the context of the declining party membership and activism that political parties face in contemporary politics. While the question of why members join parties has been well-documented, considerably less work has considered incentives to join other party positions. In the Canadian case, for example, we know very little about the incentives to join an electoral district association (EDA). This is surprising given the consequential role—both formal and informal—that local party associations and their presidents have been known to play in intra-party politics (influencing candidate nomination, membership recruitment and so forth). This study applies Clark and Wilson's (1961) framework of material, solidary and purposive incentives to local party association membership and asks why individuals join their local party executive and whether this motivation shapes the subsequent character of the EDA.
