Oh Se-hoon's Presidential Bid vs. Imprisonment Sentence Demand: The Two Faces of the Seoul Mayor

\n

Why is Oh Se-hoon gaining attention as the leading conservative presidential candidate?

Oh Se-hoon, the Mayor of Seoul, has surged to the top spot in polls for next presidential suitability. Yet, at the same time, he faces a career-shaking risk: the trial over allegations of illicitly covering public opinion survey costs linked to Myung Tae-kyun. The stark clash between a peak in momentum and looming legal uncertainty within a single figure is precisely why Oh Se-hoon is the hottest name right now.

Why has Oh Se-hoon suddenly risen as the ‘number one conservative’?

Recent surveys place Oh Se-hoon as the most prominent contender within the conservative camp. This is more than just “high name recognition”—the numbers consistently confirm his lead. Particularly, the concentration of support among conservative voters carries immense weight in the party’s primary race. In short, Oh Se-hoon is moving beyond “Mayor of Seoul” to become the centerpiece of the presidential candidate lineup.

Why is the ‘trial risk’ hanging over Oh Se-hoon so fatal?

The critical factor is speed. The accelerating rise in his approval ratings is matched by the rapid approach of the trial risk.

• The issue revolves around the alleged illegal payment for public opinion survey expenses around the 2021 Seoul mayoral by-election (violation of political funding laws)
• The special prosecutor has demanded 1 year and 6 months imprisonment and a fine of 33 million won from Oh Se-hoon
• Should he be sentenced to a fine of over 1 million won or higher, it could directly lead to disqualification and loss of his mayoral position

In other words, this trial is not merely an image problem—it is a matter that could cost him his office, which instantly threatens his eligibility to run for president.

Oh Se-hoon’s fate could hinge not on political trends, but on a single courtroom verdict line

Here lies the intriguing point. While Oh Se-hoon rises as the conservative front-runner, he is simultaneously at risk of having his entire political schedule halted depending on the severity of the verdict.
Looking ahead, the key points to watch are clear:

• Whether he is found guilty or not matters, but in real politics, the most decisive factor is the ‘1 million won fine borderline’.
• An acquittal or a light sentence could frame him as a “candidate who endured political investigation,”
• Whereas a confirmed sentence resulting in dismissal could instantly turn Oh Se-hoon from front-runner into a political exit variable.

The most accurate way to describe Oh Se-hoon right now is this:
“He is both the leading candidate in the presidential race and simultaneously a figure whose future can be reset entirely by one court ruling.”

Oh Se-hoon’s Political Journey: From the Grand National Party to a Three-Term Seoul Mayor

Originating from the Grand National Party (the predecessor of the current People Power Party), Oh Se-hoon is recognized as a figure standing on the trajectory of a ‘traditional conservative politician,’ yet he has expanded popular support by blending centrist urban policies with image-driven politics while managing the massive city of Seoul. While rooted in conservative principles, he has repeatedly crafted the message of “pragmatism over ideology” through urban agendas.

His career is marked by a striking fall and comeback. After facing political damage following his resignation in 2011 over the free school meals referendum, Oh returned to the spotlight by winning the 2021 by-election and securing re-election thereafter—completing a three-term tenure as Seoul mayor. In this journey, he built a narrative as an “administrator who faced failure but proved himself again,” which also became a symbol of political resilience.

Oh Se-hoon as an Urban Administrator: Coexistence of Centrist Policies and a Conservative Image

Oh’s strength lies in maintaining his ‘conservative’ identity while prominently advancing relatively non-ideological issues in Seoul’s governance, such as urban design, environment, and development visions. Policies like easing redevelopment and reconstruction regulations, increasing housing supply, and Han Riverfront development resonate with conservative supporters, yet can easily be framed under the theme of “urban growth.” In other words, these were choices aimed at both consolidating his base and broadening his appeal.

A crucial point here is not only the ‘policies themselves’ but also the leadership style surrounding them. Oh skillfully positions himself not as an ideological politician but as a manager running the city, a stance that gains particular strength when linked with symbolic evaluations such as being “presidential material.” However, in conflict-ridden issues like the TBS restructuring controversy, the very image that favored centrism faces challenges. Ultimately, Oh Se-hoon’s popular support has been built by layering “the stability of conservatism” with “pragmatism in urban administration,” and the key factor going forward will be how convincingly he maintains that balance.

Key Issues in Oh Se-hoon’s Administration: From Redevelopment to TBS Conflicts

Seoul’s housing prices and media have always been the “immediate trigger buttons” in politics. This is precisely why Oh Se-hoon’s administration draws so much attention. The easing of reconstruction and redevelopment regulations quickly raised conservative expectations, but at the same time, fierce debates over the side effects of development and conflicts concerning the public media outlet TBS sparked direct clashes with the progressive camp. Why do these intense confrontations keep repeating?

Oh Se-hoon’s Redevelopment and Reconstruction Drive: “Expanding Supply” vs. “Urban Inequality”

Oh Se-hoon’s urban policy can be summed up in one phrase: deregulation and accelerating development. The points that excite his supporters are clear.

• Expectations for expanded housing supply: Lowering the barriers for reconstruction and redevelopment is seen as a solution to Seoul’s chronic supply shortage.
• Psychology of asset value recovery: Especially in Gangnam and areas with vested interests in redevelopment projects, policy changes often translate directly into perceived financial gains.
• Urban competitiveness narrative: Large-scale projects along the Han River create a compelling story of “revitalizing Seoul.”

However, the points of conflict are just as vivid.

• Controversy over concentrated development profits: When deregulation benefits specific areas or social classes, the policy quickly attracts the “tax cuts for the rich” and “pro-rich policies” criticism.
• Gentrification and displacement issues: Accelerated redevelopment tends to cause rent hikes and displacement, unsettling the livelihoods of original residents.
• Environmental and landscape disputes: Development along the Han River and downtown areas sparks debates over environment, views, and public interests, igniting ideological clashes.

In short, for conservatives, it’s a “policy showing tangible results,” while for progressives, it reads as a “policy that accelerates inequality,” making the same policy evoke fundamentally opposite political emotions.

The Conflict Between Oh Se-hoon and TBS: Administrative Reform or Political Pressure?

Another major axis is the conflict over cutting support and restructuring TBS. This issue transcends a simple budget debate, evolving into a symbolic war over ‘public media independence’ and ‘political interference.’

• Conservative perspective: It’s framed as “a process to normalize a biased affiliated media,” emphasizing the legitimacy of tax funding and management accountability.
• Progressive perspective: It’s seen as “a way to tame a critical media outlet,” fueling suspicions of pressure wielded through administrative powers. The freedom of the press frame immediately comes into play.

This context also explains why some voices within the media industry call for inclusive leadership to ease the conflict. Because TBS symbolizes “the relationship between power and critical media” more than policy details, once clashes occur, compromise becomes extremely difficult.

Political Impact of Oh Se-hoon’s Administration: Easy to Rally Supporters, Hard to Expand

The redevelopment/reconstruction and TBS issues share a common trait: they strongly mobilize conservative bases, yet face strong resistance when trying to reach centrists and progressives.
Considering Oh Se-hoon’s attempt to expand the middle ground by projecting himself as an ‘urban administrator,’ these two issues are likely to remain crucial tests of his leadership moving forward.

Oh Se-hoon’s Poll Lead and Presidential Bid Collide Head-On with Political Funds Act Trial

A decisive “brake” has suddenly slammed on Oh Se-hoon, the Mayor of Seoul, who had been leading the race for the presidency. While recent polls have clearly positioned him not only as a leading conservative contender but also among the front-runners overall, the political funds law trial over the alleged ‘Myung Tae-gyun poll payment cover-up’ has emerged as the darkest cloud threatening his future. The core issue surrounding Oh Se-hoon now is not simply that “his approval ratings have risen,” but that his upward trajectory is colliding head-on with serious legal risks at the very same moment.

What Oh Se-hoon’s Rise Means: The Presidential Race Becoming Reality

Rising poll numbers signal that politics is moving from mere “imagination” to “preparation.” Oh Se-hoon is consistently placing at the top tier in various surveys, planting the seeds of a dominant trend within the conservative camp. The key point here is that it’s not just about the numbers themselves—it’s how those figures are rewriting the rules of the party’s nomination process.

• Moves like managing inside-party networks and expanding contacts within the assembly are read not as casual social gestures but as “network-building steps preceding a formal campaign.”
• As support from the conservative base solidifies, rival candidates increasingly view Oh as a contender they must actively check.

In other words, Oh Se-hoon’s presidential bid has already shifted from speculation to a real political variable.

The Immediate Stop Risk Posed by Oh Se-hoon’s Political Funds Trial

The problem is that alongside his rapid rise, the risk he faces is equally stark and direct. Oh is on trial for allegedly commissioning opinion polls from Myung Tae-gyun ahead of the 2021 Seoul mayoral by-election and having a supporter cover the associated cost of 33 million KRW, a violation of the Political Funds Act. The special prosecutor’s office has demanded a prison term of 1 year and 6 months plus a fine of 33 million KRW at the sentencing hearing.

What makes this trial so critical is not just a battle over narratives but that its outcome could instantly affect his position and eligibility.

• A confirmed sentence involving a fine exceeding 1 million KRW can lead to disqualification from office and loss of his mayoral post.
• His bid for the presidency could then evolve from mere “image damage” to outright exclusion from the race.

This staggering political cost is why Oh strongly denies all allegations, calling the investigation a “directed probe and politically motivated prosecution.”

How the Verdict Could Reshape the Presidential Race: Two Diverging Scenarios

The court’s decision will do more than determine personal guilt or innocence; it could dramatically redraw the conservative camp’s political map.

• Acquittal or fine under 1 million KRW
  Oh could be seen as a contender who has “survived risk,” possibly gaining momentum, especially if his support base consolidates. This scenario allows him to maintain or even boost his position in the presidential race.
• Confirmed fine above 1 million KRW (or an equivalently serious ruling)
  This would raise the possibility of a mayoral re-election and force the conservative camp into a frantic search for a replacement and internal power reshuffle. In this case, the presidential race would not center on Oh Se-hoon but rather on who fills the vacuum left by his absence.

Ultimately, Oh Se-hoon is simultaneously pressing the accelerator of his top poll position while gripping the emergency brake of his legal battle. With a single ruling capable of altering Seoul’s administration, the conservative leadership landscape, and next election strategies, this clash is poised to remain one of Korean politics’ most compelling storylines for the foreseeable future.

The Political Crossroads of Oh Se-hoon: The Lasting Impact and Prospects of His Trial Outcome

Will the fine exceed 1 million won, or will it result in acquittal? This single line of conclusion is not just the end of the case—it marks a pivotal juncture that determines both the continuation of the Seoul mayoral office and the possibility of a presidential bid. For Oh Se-hoon, this trial is not merely an “image blow,” but a verdict that could decide his very political survival.

The Crucial Checkpoint of Oh Se-hoon’s Trial: The Political Boundary of ‘1 Million Won’

The cold, hard criterion in this case is simple: whether the violation of the Political Funds Act is confirmed, and if so, whether the resulting fine is 1 million won or more.
In cases related to public office elections and political funds, this threshold is fatal. If a sentence exceeding 1 million won is confirmed, it can lead to disqualification from office and loss of position. Ultimately, this trial is a battle that goes beyond “guilty or not guilty”—it’s a fight over whether he crosses the political survival line.

Impact by Verdict Scenario: What Remains for Oh Se-hoon?

The ruling is likely to create political aftershocks in three distinct ways.

• Not Guilty or Insufficient Evidence
  Oh Se-hoon can shake off the “judicial risk” and even gain the narrative of being a “figure who overcame the onslaught.” This would legitimize the prevailing trend within the conservative camp and could accelerate his presidential ambitions.

• Guilty but Fine Below 1 Million Won (or at a Level That Doesn’t Lead to Disqualification)
  Although legally he escapes critical damage, politically it leaves an ambiguous picture. The opposing camp will highlight the “guilty” verdict itself, while supporters defend with “he still endured” — leading to a prolonged war of narratives. The key point is the potential shakiness of his ‘expansion’ prospects in the presidential race.

• Confirmed Fine of 1 Million Won or More (Disqualification Risk Materializes)
  This outcome would cause more than just a single shockwave. It would trigger a cascade reaction including a vacuum in Seoul’s administration, the variable of a by-election, and a reorganization of succession dynamics within the People Power Party. Beyond Oh’s personal issue, the entire conservative presidential landscape could be reshaped.

Simultaneous Test for Seoul’s Governance and National Ambitions: The ‘Trace of Leadership’ Remains

An important question remains even as the trial proceeds: how will Oh Se-hoon steer the city government amid crisis?
Long-term policies like redevelopment and reconstruction hinge on continuity, while sensitive conflict issues including TBS reveal layers of leadership style. Even if the legal conclusion favors him, if his conflict management and coalition-building abilities falter during the process, his assessment as a “presidential candidate” will suffer. Conversely, if he demonstrates stability in policy management amid adversity, that could become a political asset independent of the trial’s result.

What We Should Watch Closely: The Politics After the Verdict, Not Just the Judgment Itself

The trial is the conclusion, but politics vibrates more fiercely after that. The three focal points for observers are:

1. The logic of the verdict: Not just guilty or not, but “what was proven and what was dismissed”
2. The conservative base’s reaction: Is it defensive consolidation or a shift toward risk avoidance?
3. Rearrangement of power within the party: Will Oh maintain and expand his influence, or will competition over his potential vacancy erupt?

In the end, this trial is both a “legal judgment” and a “preview of political judgment” for Oh Se-hoon. The significance of the single figure of 1 million won lies in its power to simultaneously overturn Seoul’s power balance and the conservative camp’s presidential landscape.
