[Asia Economy Reporter Oh Ju-yeon] A poll showed that Gyeonggi Province Governor Lee Jae-myung held an advantage in hypothetical one-on-one matchups against other opposition presidential candidates, except for former Prosecutor General Yoon Seok-youl.


On the 13th, Realmeter, a polling agency, conducted a survey commissioned by OhmyNews on the 11th and 12th, targeting 1,012 men and women nationwide aged 18 and older. The results showed that in a one-on-one contest between Governor Lee and former Prosecutor General Yoon, 45.7% said they would vote for Yoon, while 35.5% said they would vote for Lee. The gap between them was 10.2 percentage points, which is outside the margin of error (±3.1 percentage points at a 95% confidence level). The undecided voters accounted for 18.8%.


By age group, 50s and 60s and older favored former Prosecutor General Yoon at rates of 50.5% and 56.2%, respectively, while in the 40s age group, 49.8% chose Governor Lee, exceeding the average response rate (35.5%). Among those in their 20s, one in four responded "none" (25.8%).


By region, more than half of respondents in Daegu·Gyeongbuk (57.8%), Seoul (55.0%), and Busan·Ulsan·Gyeongnam (53.0%) said they would vote for former Prosecutor General Yoon, whereas in Gwangju·Jeolla, 58.4% chose Governor Lee, showing a contrasting pattern depending on the region.


Although Governor Lee was behind in the one-on-one matchup against former Prosecutor General Yoon, he showed an advantage in all one-on-one contests against other opposition presidential candidates.


In a hypothetical one-on-one contest with Representative Hong Joon-pyo, Governor Lee received 38.4% support, leading Hong (27.1%) by 11.3 percentage points. Against Ahn Cheol-soo, leader of the People’s Party, Lee garnered 37.8%, beating Ahn (28.8%) by 9.0 percentage points.


Additionally, in a contest with Representative Yoo Seung-min, Governor Lee received 37.9%, leading Yoo (19.2%) by 18.7 percentage points.
