The Democratic Party of Korea’s race for the Jeju gubernatorial nomination has entered a critical final phase, as candidates Wi Seong-gon and Moon Dae-rim advance to a runoff election. The development follows a surprising turn of events in the primary process, where the incumbent Governor Oh Young-hun failed to secure a spot in the final round.
The Democratic Party Jeju governor primary runoff is now the central focus of the province’s political landscape. With the incumbent eliminated, the party is moving toward a decisive vote to determine who will represent them in the upcoming June 3 local elections. This shift signals a potential change in leadership for the island province, as the party seeks a candidate who can consolidate support across its diverse base.
According to official announcements from the party’s election management committee, the runoff will take place from April 16 to April 18. This decision was triggered because no single candidate achieved a majority of the votes during the initial primary round, which ran from April 8 to April 10 per reports from Kyunghyang Shinmun.
The primary process utilized a “national participation” model, combining 50% weight from party members’ votes and 50% from public opinion polls. While the specific vote tallies for each candidate remain confidential under party rules, the outcome has created a high-stakes showdown between the two remaining lawmakers.
The Fall of the Incumbent: Why Governor Oh Young-hun Was Eliminated
The most significant outcome of the primary is the elimination of Governor Oh Young-hun. In a political environment where incumbents typically hold a strong advantage, Oh’s failure to reach the runoff is being viewed as a major upset. Several factors contributed to this result, most notably a strict penalty imposed by the party’s nomination management committee.

Reports indicate that Governor Oh received a low evaluation following an interview with the nomination committee, ranking as the lowest among five Democratic Party regional heads. This resulted in a 20% deduction of his total votes as detailed by Straight News. Despite filing an objection, the penalty remained in place, which analysts suggest was the deciding factor in a tight three-way race.
The tension during the primary was further exacerbated by mutual accusations among the three candidates. During a joint briefing on April 6, the candidates clashed over several contentious issues, including allegations regarding the closure of the provincial government office during the December 3 insurrection, suspicions of government-led election interference, and the distribution of “ghost messages” (anonymous texts) intended to sway voters according to Kyunghyang Shinmun.
The Final Contenders: Wi Seong-gon and Moon Dae-rim
With the incumbent out of the picture, the race has narrowed to two members of the National Assembly: Wi Seong-gon, who represents Seogwipo, and Moon Dae-rim, who represents Jeju City Gap per Media Today.
Representative Wi Seong-gon has framed his advancement as a mandate for change. Shortly after the results were announced on April 10, Wi expressed his gratitude on Facebook, stating that he would embrace the “longing for change” reflected in the votes of the provincial residents and party members. He pledged to prove through his capabilities that he is the most reliable “tool” for the people of Jeju via Kyunghyang Shinmun.
Representative Moon Dae-rim also took to social media to acknowledge the gravity of the situation. Moon described the decision to send him to the runoff as a “desperate will” from the voters, which he intends to honor with a sense of heavy responsibility. He has vowed to achieve a “new transition” for Jeju through an overwhelming victory in the final vote via Kyunghyang Shinmun.

Strategic Shifts: Unity and Consolidation
As the runoff approaches, the strategy for the remaining candidates has shifted toward consolidating the fragmented support of the party. Because the primary was a three-way split, the candidate who can successfully integrate the supporters of the eliminated Governor Oh Young-hun is likely to hold a significant advantage.
The focus has now turned to a “single-file” approach to unity. This strategy involves bridging the gap between different factions within the provincial party to ensure that the Democratic Party enters the general local election on June 3 as a cohesive unit rather than a divided front.
The runoff will be conducted exclusively between Wi Seong-gon and Moon Dae-rim. The winner of this vote will officially become the Democratic Party’s candidate for the Jeju Governor’s office, tasked with winning the general election and managing the complex political dynamics of the region.
For those following the developments, the final nominee will be confirmed following the conclusion of the runoff on April 18. This will be the final checkpoint before the party shifts its resources toward the general campaign for the June 3 elections.
