South Korea's ruling Democratic Party won the majority of local races in elections held Wednesday, June 3, 2026.
The results signal broad public support for President Lee Jae Myung's liberal administration while highlighting a persistent conservative stronghold in the capital city.
The Democratic Party (DP) secured the largest share of votes in 12 of the 16 regions [1]. This regional sweep reflects a general trend of support for the current government's policies across the country. Prior to the elections, President Lee Jae Myung held an approval rating of 59.8% [2].
Despite the nationwide success, the DP failed to capture the Seoul mayoralty. Incumbent conservative mayor Oh Se-hoon won the high-profile contest, maintaining opposition control over the capital [1]. The loss in Seoul serves as a symbolic setback for the ruling party, as the city remains a critical center of political and economic power.
Local dynamics in Seoul favored the incumbent, whereas the broader national mood benefited the DP candidates [1]. The results underscore a geographic divide between the capital's preferences and those of the other regional jurisdictions.
The elections were conducted across all 16 regional jurisdictions, with early vote counts reported on June 4 [1]. The outcome cements the ruling party's influence over local governance in most of the country, even as it faces a continued challenge from conservative leadership in the heart of the nation.

The election results demonstrate a dual political reality in South Korea: a strong national mandate for President Lee Jae Myung's liberal agenda and a resilient conservative bastion in Seoul. While the ruling party's regional dominance provides a stable platform for implementing national policy, the failure to flip the capital suggests that the opposition remains a potent force in urban centers, potentially limiting the administration's total political hegemony.
