Why do party leaders prefer the convention system?

Party leaders prefer the convention system because it allows for greater control over the nomination process, enabling them to manage candidate selection and maintain party unity. Conventions provide a platform for leaders to rally support, showcase party values, and build momentum for the general election. Additionally, this system can help mitigate intra-party conflicts by fostering a collaborative atmosphere among delegates and party members. Overall, conventions serve as a strategic tool for consolidating power and resources within the party.
