In 1948, MacArthur made a bid to win the Republican nomination to be the GOP candidate for president, which was the most serious of several efforts he made over the years. MacArthur's status as one of America's most popular war heroes together with his reputation as the statesman who had "transformed" Japan gave him a strong basis for running for president, but MacArthur's lack of connections within the GOP were a major handicap. MacArthur's strongest supporters came from the quasi-isolationist, Midwestern wing of the Republicans and embraced men such as Brigadier General Hanford MacNider, Philip La Follette, and Brigadier General Robert E. Wood, a diverse collection of "Old Right" and Progressive Republicans only united by a belief that the U.S. was too much involved in Europe for its own good. MacArthur declined to campaign for the presidency himself, but he privately encouraged his supporters to put his name on the ballot. MacArthur had always stated he would retire when a peace treaty was signed with Japan, and his push in the fall of 1947 to have the U.S sign a peace treaty with Japan was intended to allow him to retire on a high note, and thus campaign for the presidency. For the same reasons, Truman subverted MacArthur's efforts to have peace treaty signed in 1947, saying that more time was needed before the U.S. could formally make peace with Japan.
