The National Electoral Committee said preliminary results will be announced at 3am on Wednesday and an official announcement of the winner is expected sometime after 8am.

The latest surveys show Moon Jae-in of the Democratic Party leading the race with 35-40% support, followed by Ahn Cheol-soo of the People’s Party and Hong Joon-pyo of the Liberty Korea Party. A survey by RealMeter showed that Korean voters are more concerned about domestic issues like corruption, political and economic reform, and their own lives than about regional issues or escalating tensions on the Korean peninsula.

During the campaign, Moon assured voters that South Korea can meet the challenges of economic stagnation, North Korea’s nuclear weapons programs, and national reform and unification. Analysts say Moon will show a friendlier face to North Korea if he is elected. Moon has said he will negotiate with North Korea and say ‘No’ to Washington, if necessary.

North Korea on Monday seemed less confrontational with South Korea, which some have read as implicit support for Moon Jae-in.
