The April 10 parliamentary elections in South Korea resulted in a landslide victory for the liberal opposition, dealing a resounding setback to President Yoon Suk Yeol and his ruling conservative People Power Party. While the liberal Democratic Party fell short of achieving a super majority, the outcome reflects pervasive public discontent with Yoon's administration amid economic challenges and political controversies, placing Yoon in a difficult position for the remainder of his three-year term.

“In a sense, this was a rematch between President Yoon and Democratic Party leader Lee Jae-myung, whom Yoon defeated in the 2022 presidential race by a razor-thin margin, and Lee won in a big way,” explains Stanford sociologist and APARC Director Gi-Wook Shin. “Now the Democratic Party really became Lee’s party.”

Shin, the William J. Perry Professor of Contemporary Korea and the director of the Korea Program at APARC, joined the Korea Society for a livestreamed election analysis session. Watch it here:

The election outcomes reflect the increased political division and polarization gripping South Korea, which is poised to be a major issue for Korean politics in the coming years, Shin notes. Shin has written extensively about the roles of illiberalism, populism, and polarization in the decline of Korean democracy and their implications for Korean society and politics.

“I have said before that Korea is facing a crisis in democracy. Now I can say that Korea is also facing a crisis in political leadership,” he tells Korea Society Policy Program Officer Chelsie Alexandre.

In this session, Shin explores in detail what the election results mean for Korea’s political, economic, and social policy, its alliance with the United States, and its relations with regional states.

Shin has also contributed to election analysis in national and international media.

Reboot of Adversarial Politics

South Korean voters’ verdict on the Yoon government’s performance reflects deep disappointment and even resentment about some of his policies and leadership styles, Shin shares with Bloomberg News. As the opposition holds a large majority in the National Assembly, Yoon appears destined to complete his remaining three years in office as a lame duck, unable to push for any major policy initiatives, domestic or foreign. We should expect a reboot of adversarial politics in South Korea as the opposition looks to obstruct Yoon’s legislative agenda, Shin predicts. 

Voter turnout for the parliamentary elections reached 67 percent, marking the highest turnout for general elections in 32 years. Liberals expressed discontent with the government by sending a strong message through voting, while the ruling conservative party tried to mobilize its supporters to minimize losses. Ultimately "there were no major policy debates between the ruling and main opposition parties," says Shin in an interview with Singaporean public broadcast service CNA.

Shin anticipates the Democratic Party will likely contest Yoon's stance toward Tokyo and Washington. Speaking with French international news agency AFP, Shin explains the potential return of former U.S. President Donald Trump, who held high-profile but unsuccessful summits with North Korean leader Kim Jong Un during his presidency, could add to the tension. If Trump were to reengage with North Korea, then the Yoon government would have to decide whether to shift from its hardline policies against the North or risk friction between Washington and Seoul, Shin says.

The election outcomes could also hinder the Yoon government’s momentum for improving ties with Japan, especially since Japanese Prime Minister Kishida, too, is facing low domestic approval ratings, Shin tells The Korea Herald. "It is unfortunate for the Korea-Japan relationship that both leaders are politically struggling."

Despite facing legal issues, controversial opposition leader Lee Jae-myung remains a leading contender for the presidency when Yoon's term ends in 2027, echoing the situation with former U.S. President Donald Trump, he tells AFP.

Gender and Generational Gaps

The parliamentary election has also brought to relief the tremendous underrepresentation of women and young people in Korean politics. Only 20% of parliamentary seats are held by women, and over 85% of elected members are over the age of 50. The older establishment and the conservative People Power Party have failed to connect with South Korea's young people, Shin says. While the country is a global cultural force and excelling in semiconductor exports, South Korea’s younger people are facing intense competition in education, limited job prospects, and soaring housing prices. “The lack of understanding of the challenges the youth face is contributing to the country's rising generational conflict,” Shin explains via AFP.
