South Korean political leaders spent the final holiday before the June 3 [1] local and parliamentary by-elections campaigning across the country.

These efforts represent the last opportunity for parties to mobilize their bases and sway undecided voters before the polls open. The results will likely signal the public's current standing on the national administration and the direction of local governance.

Jeong Cheong-rae, leader of the Democratic Party, toured South Jeolla Province, the Chungcheong region—specifically Geumsan in South Chungcheong Province—and central Seoul. During his visits, Jeong called for support to establish a "strong ruling party" [1].

Addressing the political climate, Jeong said, "The remaining embers of rebellion must be removed. If you leave the embers, again..." [1].

Simultaneously, Jang Dong-hyuk, leader of the People Power Party, focused his efforts on the downtown areas of Seoul. Jang said in the capital to call for a "judgment of the Lee Jae-myung administration" [1].

Both leaders spent the day traversing key districts to maximize voter turnout. The coordination of these tours across different regions highlights the strategic importance of the Chungcheong and Jeolla provinces, as well as the Seoul metropolitan area, in determining the overall outcome of the June 3 [1] vote.

The results will likely signal the public's current standing on the national administration.

The starkly different messaging from the two party leaders—one focusing on the strength of the ruling party and the other on a referendum against the current administration—underscores a deeply polarized political environment. Because these elections include both local seats and parliamentary by-elections, the results will serve as a critical barometer for legislative power and public sentiment heading into the next major political cycle.
