President Lee Jae-myung's Democratic Party commands a 27-point advantage over the conservative opposition ahead of South Korea's June 3 local elections, according to new polling that suggests a political realignment extending even into traditionally conservative strongholds.
The survey, conducted by the Hankyoreh newspaper and the Korean Association of Party Studies, found that 51.3% of respondents would vote for Democratic Party candidates for mayor or governor in their districts, compared to just 23.7% supporting the opposition People Power Party—a gap that has widened significantly since December 2025.
"This represents more than a preference—it suggests a fundamental shift in Korean political geography," observed one Seoul-based political analyst. The Democratic Party's penetration into conservative regions, particularly securing 40.2% approval in Daegu and North Gyeongsang Province compared to the PPP's 30.1%, marks a historic reversal in areas that have reliably supported conservative parties for generations.
The polling was conducted May 6-10 with 1,701 respondents as part of the Hankyoreh's 38th anniversary coverage, according to the newspaper's report. The results reveal not just voting intentions but governing expectations: 53.3% of Koreans want the ruling liberal bloc to win for "stable governance," while only 34.1% prefer the opposition to "keep the administration in check."
President Lee's 66.9% approval rating—more than double his disapproval rate of 28.7%—appears to be driving the Democratic surge. The former mayor of Seongnam and Gyeonggi Province governor has maintained strong public support through economic policies emphasizing wealth redistribution, expanded social programs, and a pragmatic approach to North Korea engagement.
The local elections carry significance beyond municipal governance. In South Korea's political system, local races serve as referendums on national leadership and often preview outcomes in subsequent legislative and presidential contests. A Democratic sweep on June 3 would consolidate 's control over the party and strengthen his hand in implementing policy initiatives that may face resistance in Korea's fractious National Assembly.
