On April 17, 2026, the Democratic Party of Korea announced the recruitment of attorney Jeon Tae-jin as its first high-profile candidate for the upcoming June 3 by-elections, positioning him to contest the Ulsan Nam constituency seat vacated by incumbent lawmaker Kim Sang-wook, who is running for mayor of Ulsan.
Jeon Tae-jin, a 55-year-old lawyer born and raised in Ulsan, was formally introduced at a ceremony held in the National Assembly building in Seoul, where party leader Chung Chong-rae presented him with a Democratic Party jacket. The move signals the party’s strategic effort to strengthen its presence in what has traditionally been a conservative stronghold in southeastern South Korea.
According to multiple verified reports, Jeon is a native of Ulsan who attended Hakseong High School before graduating from Seoul National University with a degree in political science. He completed his judicial training as part of the 33rd class of the Judicial Research and Training Institute and began his legal career at the law firm Jungse before becoming the representative attorney at Dongheon Law Firm.
His professional background includes extensive advisory and litigation work for key South Korean government agencies, including the Presidential Office, the Broadcasting and Communications Commission, the Ministry of Trade, Industry and Energy, the Ministry of Land, Infrastructure and Transport, the Ministry of Environment, and the National Police Agency. More recently, he has provided legal counsel to the Ministry of Culture, Sports and Tourism and the Cultural Heritage Administration.
Speaking at the announcement event, Chung Chong-rae emphasized the need for change in Ulsan, stating that the city requires new leadership to overcome entrenched regionalism and drive generational renewal. “Ulsan needs someone who can break outdated local power structures and bring in a fresh wind — a blue wind — for the future,” Chung said, adding that Jeon Tae-jin embodies that vision.
Jeon himself described his motivation in terms of practical governance, saying he aims to move beyond ideological divides to deliver results-oriented politics that maximize Ulsan’s potential and improve residents’ lives. He highlighted the city’s current challenges, including industrial decline and broader regional struggles, arguing that Ulsan must adapt to the demands of the Fourth Industrial Revolution and the AI era through structural economic reform, urban regeneration, and modernization of infrastructure.
The June 3 by-election in Ulsan Nam will be held concurrently with nationwide local elections, making it a significant political test for both the ruling and opposition parties. Democratic Party officials have framed Jeon’s candidacy as a pivotal opportunity to contest a district long dominated by conservative forces, particularly given Kim Sang-wook’s decision to step down from the National Assembly to pursue the mayoral race.
Political analysts note that the Democratic Party’s push in Ulsan Nam reflects a broader strategy to expand its footprint in traditionally difficult regions by fielding candidates with strong local roots and technocratic appeal. Jeon’s profile — as a lifelong Ulsan resident with national-level policy experience — aligns with this approach, combining local authenticity with expertise in governance and administrative law.
As the campaign period advances, Jeon is expected to focus on economic revitalization, job creation in emerging sectors, and policies supporting slight and medium enterprises, which form a critical part of Ulsan’s industrial base. His legal background may also shape his legislative priorities, particularly in areas involving regulatory reform, government accountability, and public sector efficiency.
The outcome of the Ulsan Nam by-election will be closely watched as an early indicator of voter sentiment ahead of the next general election, with both parties mobilizing resources to secure what could be a symbolic shift in one of South Korea’s key industrial centers.
