After former United Nations Secretary-General Ban Ki-moon announced that he would not seek to become the next president of South Korea, South Korea’s ruling conservatives were left without a clear candidate to succeed the beleaguered President Park Geun-hye. From Rhee In-je to Won Yoo-chul, there isn’t a single conservative candidate left who has a realistic chance of becoming the next South Korean president if the election were held today.

What that means is that Moon Jae-in, with a little over 33% in his approval ratings, has the best chance of becoming the next South Korean president. Just in case anyone has forgotten, Moon Jae-in was President Roh Moo-hyun’s chief-of-staff and, according to former Foreign Minister Song Min-soon’s memoirs, he agreed to ask the North Korean government how South Korea ought to vote in a 2007 UN General Assembly vote that condemned North Korea’s atrocities against its own people.
