If the presidential election were held now, Lee Jae-myung, the presidential candidate of the Democratic Party of Korea, would record over 50% support in all hypothetical head-to-head matchups against Kim Moon-soo, the presidential candidate of the People Power Party, Han Duck-soo, an independent presidential preliminary candidate, and Lee Jun-seok, the presidential candidate of the Reform Party.
Korea Gallup conducted a phone interview poll of 1,006 adults aged 18 and older nationwide from April 3 to 4 at the request of JoongAng Ilbo and released the results on April 6.
In a hypothetical head-to-head matchup between Lee and Kim, Lee recorded 52%, ahead of Kim's 39% by 13 percentage points. In a head-to-head matchup against Han, Lee received 51% while Han received 41%. In a matchup against Lee Jun-seok, Lee Jae-myung garnered 51%, while Lee Jun-seok received 29%.
In a hypothetical three-way matchup, Lee Jae-myung had 49%, Kim Moon-soo 33%, and Lee Jun-seok 9%. In a hypothetical matchup with Han Duck-soo, Lee Jae-myung had 49%, Han 36%, and Lee Jun-seok 6%. In a hypothetical four-way matchup, Lee Jae-myung received 47%, Han Duck-soo 23%, Kim Moon-soo 13%, and Lee Jun-seok 4%.
In this survey, among the candidates suitable for unification in the conservative bloc, Han Duck-soo received 39%, leading Kim Moon-soo (30%) outside the margin of error. Notably, among the supporters of the People Power Party, Han received 65% while Kim received 27%.
Meanwhile, in this survey, when asked about the Supreme Court's ruling on the election law case involving Lee Jae-myung on April 1, 46% responded that it was a "good ruling" while 42% said it was a "bad ruling." This survey was conducted over two days from April 3, two days after the Supreme Court's ruling.
Especially among generations, the proportion of those responding "good ruling" was overwhelmingly high among those in their 20s and 30s. In the 20s, the response "good ruling" was 51%, while the response "bad ruling" was only 24%. In the 30s, it was 56% for "good ruling" and 30% for "bad ruling."
This survey was conducted using a mobile phone interview method, with a margin of error of ±3.1 percentage points at a 95% confidence level and a response rate of 17.8%. For more details, refer to the website of the Central Election Survey Deliberation Committee.
