Internal party dynamics within South Korea’s ruling Democratic Party center on Jung Chung-rae’s leadership tenure, which began after his election as chair in August 2025. The next national convention scheduled for August 2026 serves as the primary decision point for renewal of his mandate. President Lee Jae-myung’s allies have actively recruited potential challengers to contest the chair position, citing recurring public missteps that have distracted from legislative priorities and local election preparations. These pressures have produced an implied probability of 80.5 percent that Jung will no longer hold the leadership role by the end of 2026, reflecting the convention’s potential to alter the party’s direction amid ongoing coalition and policy pressures.
