As the June 3 local elections approach, Oh Se-hoon, the People Power Party candidate for Seoul mayor, is rapidly closing the gap with Jung Won-o, the Democratic Party candidate.

A poll conducted by the Korea Social Opinion Institute (KSOI) for CBS from May 12 to 13 among 1,002 residents of Seoul aged 18 and older showed Jung's support at 44.9% and Oh's at 39.8%.
 
The current gap of 5.1 percentage points is a significant narrowing compared to the previous poll conducted on April 22-23, which showed Jung at 45.6% and Oh at 35.4%, reflecting a 10.2-point difference.
 
Notably, there has been a shift among centrist voters. Jung's support dropped by 0.5 percentage points to 48.4%, while Oh's increased by 5.3 points to 38.3%. Among progressive voters, 87.8% support Jung, while 70.4% of conservative voters back Oh.
 
The percentage of respondents indicating they would choose a ruling party candidate has decreased to 44.0%, down 2.6 points from the previous survey. Conversely, the proportion of those favoring an opposition candidate rose by 5.2 points to 42.4%. Those unsure accounted for 13.7%.
 
This trend suggests that as the election date approaches, support is consolidating among both progressive and conservative bases, with some centrist voters shifting toward Oh. Additionally, 89.1% of respondents expressed a strong intention to vote.
 
In terms of party support, the Democratic Party stands at 38.9%, the People Power Party at 32.9%, the Reform Party at 4.4%, the Justice Party at 2.5%, and the Progressive Party at 2.1%.
