Labour government, 1974–1979
In March 1976, having just turned sixty years old, Wilson resigned as Prime Minister, ending his leadership of the Labour Party after thirteen years, and a total of nearly eight years as Prime Minister. He was replaced by James Callaghan, who had held senior government positions during both of Wilson's ministries, and had served as a Shadow Cabinet member in the early-1960s.
Presidency of Woodrow Wilson
Despite grave doubts about his health and mental capacity, Wilson served the remainder of his second term and unsuccessfully sought his party's nomination for a third term. In the 1920 presidential election, Republican Warren G. Harding defeated Democratic nominee James M. Cox in a landslide, and Harding succeeded Wilson in March 1921. Historians and political scientists rank Wilson as an above-average president, and his presidency was an important forerunner of modern American liberalism. However, Wilson has also been criticized for his racist views and actions.
