Democratic Party candidate Song Young-gil said he would not discuss the issue of unification with the Innovation Party for the first year after taking office and would focus on expanding the outreach to the 2030 generation. He also plans to ease the requirements for forming a negotiating group to 10 seats to create an environment where progressive parties such as the Innovation Party can be active. He countered candidate Jung Chung-rae's remarks that "only swing voters exist" and emphasized the importance of centrist politics. Song argued against Jung's "self-centered politics," saying that the Democratic Party should cooperate with the president and act as a mediator between the people and the party. To solve the real estate problem, he proposed prioritizing supply expansion and providing financial support to young people. Song emphasized his "legitimacy" by stating that he has maintained close relationships with four past presidents.
