Political and diplomatic career
His father was
John James Davis, a
West Virginia legislator who had helped create the state as a delegate to the
Wheeling Convention but who had supported slavery and opposed ratification of the
15th Amendment. Davis acquired much of his father's conservative politics, opposing women's suffrage, child-labor laws, anti-lynching legislation and
Harry S. Truman's civil rights program while privately defending the poll tax and questioning whether
African-Americans should be allowed to vote. He also maintained his father's staunch allegiance to the
Democratic Party, even as he later represented the interests of conservative business interests opposed to the
New Deal. Davis ranked as one of the last
Jeffersonians; supporting states rights and opposing a strong executive (he would be the lead attorney against Truman's nationalization of the steel industry).
He represented West Virginia in the
U.S. House of Representatives from 1911 to 1913, where he was one of the authors of the
Clayton Act. Davis also served as one of the managers in the successful
impeachment trial of Judge
Robert W. Archbald. He served as
U.S. Solicitor General from 1913 to 1918 and as
ambassador to the
United Kingdom from 1918 to 1921. As Solicitor General he successfully argued for the illegality of Oklahoma's "grandfather law", which effectively disenfranchised most black citizens of Oklahoma by exempting white residents descended from a voter who had been registered in 1866 from the literacy requirements of its electoral law, in
Guinn v. United States. Davis's personal posture differed from his position as an advocate. Throughout his career, he could separate his personal views and professional advocacy.
Davis was a
dark horse candidate for the Democratic nomination for President in both 1920 and 1924. He won the nomination in 1924 as a compromise candidate on the one hundred and third ballot. His denunciation of the
Ku Klux Klan and his prior defense of black voting rights as Solicitor General under
Wilson cost him votes in the
South and among conservative Democrats elsewhere. He lost in a landslide to Coolidge, who did not leave his house to campaign.
Davis was a member of the National Advisory Council of the Crusaders, an influential organization that promoted the
repeal of prohibition. He was the founding President of the
Council on Foreign Relations, formed in 1921, and a trustee of the
Rockefeller Foundation from 1922 to 1939.
