South Korean President Lee Myung-bak exits from a voting booth to cast his ballot in South Korea's presidential election at a polling station in Seoul on Wednesday, Dec. 19, 2012. South Koreans bundled in thick mufflers and parkas braved frigid weather to choose between the liberal son of North Korean refugees and the conservative daughter of a late dictator. For all their differences, the presidential candidates hold similar views on the need to engage with Pyongyang and other issues. (AP Photo/Ahn Young-joon, Pool)
