Lee Jae-myung, the presidential nominee of the ruling Democratic Party (DP), is trailing both leading opposition contenders in hypothetical two-way matchups, a survey showed Thursday.

Lee earned 38.9 percent against 44.4 percent for Rep. Hong Joon-pyo of the main opposition People Power Party (PPP), according to the survey of 2,035 adults conducted Monday and Tuesday by Realmeter.

In a matchup with PPP contender Yoon Seok-youl, Lee garnered 40.9 percent against Yoon's 45.3 percent.

The difference with Hong was outside the margin of error of plus or minus 2.2 percentage points at the 95 percent confidence level. With Yoon, the difference was within the margin.

Lee also lost out to former Jeju Gov. Won Hee-ryong of the PPP in a hypothetical two-way race with 40.1 percent against Won's 43.8 percent.

The only PPP contender he led was former Rep. Yoo Seong-min with 40 percent against Yoo's 36.1 percent.

In a four-way race that included members of minor parties, Lee maintained a narrow lead over both Hong and Yoon.

With Yoon as the PPP nominee, Lee had 34.6 percent support against Yoon's 34.4 percent. With Hong as the nominee, Lee beat the lawmaker 34.4 percent to 29.3 percent. (Yonhap)
