A Mini Presidential-Scale Race: 5 Meanings the Seoul Mayoral Primary — With D-89 Candidate Lineup Confirmed at the Public Office Resignation Deadline — Holds for Korean Politics
On March 6, D-89 before the June 3 local elections and the legal deadline for public officials to resign, the Seoul mayoral primary lineup came into focus. In the People Power Party, incumbent Oh Se-hoon faces challenges from Na Kyung-won and Yoon Hee-sook, while the Democratic Party sees Jung Won-oh, Park Ju-min, Jeon Hyun-hee, and others entering the race, creating what insiders are calling a 'mini presidential-scale' contest.
Why You Need to Watch This Now: Today (March 6) is the legal deadline for public officials who wish to run in the June 3 local elections to resign. The Seoul mayoral primary has officially entered its 'confirmed lineup' phase.
TL;DR
- D-89 until the June 3 local elections. Today's public office resignation deadline has locked in the candidate picture.
- People Power Party (PPP): Oh Se-hoon (seeking a 5th term) vs. Na Kyung-won, Shin Dong-wook, and Yoon Hee-sook — the party plans to build this into a 'mini presidential-scale' event.
- Democratic Party (DP): Former Seongdong District Mayor Jung Won-oh, Rep. Park Ju-min, Rep. Jeon Hyun-hee, Rep. Kim Young-bae, and others have announced primary bids.
- In Busan, a showdown between DP's Rep. Jeon Jae-su and incumbent Mayor Park Hyung-jun appears likely.
- These local elections represent the first nationwide 'midterm evaluation' of the Lee Jae-myung administration and are directly tied to the next presidential race dynamics.
The Facts: What Happened Today?
Under the Public Official Election Act, public officials wishing to run in local elections must complete their resignation by D-90 before election day, which was March 5. As of today (March 6, D-89), the distinction between those "in the race" and those "watching from the sidelines" has been officially drawn.
Current State of the Seoul Mayoral Race:
| Candidate | Party | Current Position | Notes |
|---|---|---|---|
| Oh Se-hoon | PPP | Seoul Mayor (incumbent) | Seeking 5th term |
| Na Kyung-won | PPP | National Assembly Member | Likely to join primary |
| Yoon Hee-sook | PPP | Former lawmaker | Officially declared candidacy on March 4 |
| Shin Dong-wook | PPP | National Assembly Member | Being mentioned for primary |
| Jung Won-oh | DP | Former Seongdong District Mayor | Resigned district mayor post and announced candidacy |
| Park Ju-min | DP | National Assembly Member | Joining primary |
| Jeon Hyun-hee | DP | National Assembly Member | Joining primary |
| Kim Young-bae | DP | National Assembly Member | Joining primary |
Why 'Mini Presidential-Scale' Now?
The Seoul mayoral seat is chosen by approximately 8.5 million eligible voters in Seoul — the largest metropolitan governorship in Korea. Historically, the Seoul mayorship has served as a springboard to the presidency (Oh Se-hoon, Park Won-soon, Lee Myung-bak, etc.).
- Directly Tied to Presidential Dynamics: For the PPP, whether Oh Se-hoon wins reelection or Na Kyung-won mounts a challenge serves as the opening shot of the next presidential race.
- Midterm Evaluation of the Lee Jae-myung Administration: For the DP, now in its second year in power, retaking Seoul is directly linked to President Lee Jae-myung's governing momentum.
- Controversy Over Nomination Process: The PPP's nomination committee is reviewing a split primary between incumbents and non-incumbents, while Oh Se-hoon's camp is pushing back, saying the party must first decide on its direction — surfacing internal divisions.
Context and Background
The June 3 local elections carry the character of not just a regional vote, but the first nationwide verdict on the Lee Jae-myung administration. The key question is whether the ruling Democratic Party can hold onto a majority of metropolitan governorships, or whether the opposition PPP can stage a comeback in Seoul and other major cities.
- The PPP's approval rating has recently hit historic lows (around 17%), making the Seoul mayoral primary a crucial test for the party's rebuilding efforts.
- In Busan, a major showdown between DP's Rep. Jeon Jae-su and incumbent Mayor Park Hyung-jun is seen as likely.
- Primaries for merged regional governments — South Jeolla/Gwangju, South Chungcheong/Daejeon, and Daegu/North Gyeongsang — are also heating up simultaneously.
Outlook: Who Will Come Out Ahead?
- Short-term (Primary): The PPP has a high likelihood of a three-way or larger primary, hoping to rally its base through an exciting contest. The DP will try to boost general election competitiveness through consolidation or an open primary.
- Medium-term (D-89 to Election Day): The fallout from the Iran war, soaring oil prices, and livelihood issues are the biggest wild cards shaking up the race. Some analysts argue that the more economic issues dominate, the worse it is for the ruling DP.
- Long-term (Presidential Race): Whoever wins the Seoul mayoralty will shift the center of gravity among candidates for the 2027 presidential election.
