Kim Koo
In 1948, the inaugural National Assembly of South Korea nominated Kim as a candidate for the office of the first president of the Republic. In the election by the National Assembly, Kim was defeated by Rhee Syngman, the first president of the provisional government, who had been impeached in 1925 by a vote of 180-16. He lost the election for the vice presidency to Lee Si-yeong (이시영; 李始榮) by a vote of 133-59. Kim did not know about his nomination until after the election. He did not approve the nomination, considering it a ploy to discredit him. Kim would never have participated in the election as he fiercely opposed the establishment of separate governments in North and South Korea.
