The Democratic Party of Korea primary election for party leader will conduct a national opinion poll from the 14th for two days. In the midst of fierce competition between candidates Kim Min-seok, Jeong Cheong-rae, and Song Young-gil, the results of the opinion poll are showing a mixed picture, making predictions difficult. Each candidate's campaign is intensifying its public relations efforts to achieve good results in the national opinion poll. As the competition intensifies, the factional conflict is also deepening instead of the leading candidates, and criticism and counterarguments regarding past political activities are continuing fiercely.
