The candidates for the Democratic Party of Korea leadership election are former representative Jung Cheong-rae, former Prime Minister Kim Min-seok, lawmaker Song Young-gil, lawmaker Go Min-jung, and former Gangjin County councilor Kim Bo-mi. Whether to introduce a preferential voting system is emerging as a key issue, with the pro-Jung faction opposing it and other candidates expressing their willingness to accept it. Although former representative Jung declared that he would not run for president, the pro-Lee faction criticized this, arguing that he had failed to fulfill his role as party leader. On the other hand, the pro-Jung faction argued in favor of Jung's decision not to run for president, citing the need for stable government support.
