[Asia Economy Reporter Koo Chae-eun] On the 10th, Lee Jae-myung, the candidate elected as the Democratic Party's presidential candidate (current Governor of Gyeonggi Province), was found to be trailing former Prosecutor General Yoon Seok-youl by 6.0 percentage points (within the margin of error) in a hypothetical matchup. Lee's approval rating did not exceed 40% due to the impact of the Daejang-dong development preferential treatment allegations, which have emerged as a 'black hole' in the presidential race.
