I think this just shows how powerful name recognition can be in a national election because I cannot think of one thing Ban Ki-moon has done at the United Nations that is noteworthy other than being the first Asian Secretary General:

U.N. Secretary-General Ban Ki-moon’s confidants have sounded out the possibility of Ban’s running for president in his native South Korea, an opposition politician claimed Monday, despite Ban’s apparent objection to get involved in local politics.

Ban’s second five-year term is set to end at the end of 2016, a year before South Koreans go to the polls to elect a new president who will replace President Park Geun-hye.

Park’s single five-year term ends in early 2018, and by law, she cannot seek re-election.

Kwon Roh-kap, an adviser to the main opposition New Politics Alliance for Democracy, claimed people seen as confidants to Ban discussed the possibility of Ban’s running for South Korea’s top office on the opposition ticket.

He said he told Ban’s confidants that he respects the U.N. chief and that the opposition should ask Ban to join the party and compete in the party’s primary for the presidential nomination for the election.  [Yonhap]
