Less is more. Exploring opportunities and challenges of digital crowdsourcing for political parties.

Background: Political parties across liberal democracies face a persistent crisis of legitimacy, representation, and membership. In response, scholars and practitioners proposed a range of deliberative reforms aimed at making parties more internally democratic. Yet such innovations have proven difficult to implement due to structural features inherent to political parties, including hierarchical organization and electoral imperatives. Similarly, digital platforms promised to revolutionize internal democracy but largely disappointed expectations. This impasse highlights the need for lighter forms of democratic engagement that may better align with the operational realities of parties. Among these alternatives, digital crowdsourcing emerges as a possible path forward. Digital crowdsourcing refers to processes in which organizations use technology to tap into people's distributed knowledge, combining bottom-up input with top-down coordination to solve problems, carry out tasks, or generate ideas.

Methods: This theoretical paper develops an analytical framework tailored to the organizational and democratic specificities of political parties. I propose a typology of digital crowdsourcing for parties based on two dimensions (policy impact and power structure) yielding four forms: vertical, performative, expressive, and democratic crowdsourcing.

Results: Thanks to this typology, I identify three core opportunities associated with the adoption of these tools: enhanced democratic participation, increased flexibility, and improved accessibility for members and supporters. Conversely, I outline three central challenges: tensions between inclusion and exclusion, risks of elite capture, and conflicts between competing sources of democratic legitimacy. Finally, I present a set of strategies for achieving a feasible democratic crowdsourcing in political parties.

Conclusion: Integrating digital democratic innovations into political parties (especially long-established ones) remains particularly challenging. However, lighter forms of participation, such as digital crowdsourcing, may be more feasible to implement.
