Mrs. Roosevelt was very interested in civil rights and tried to anti-lynching legislation through the Congress. She used her position as first lady to push for equal rights at every opportunity. However, it wasn't until the 1948 convention, which nominated Harry Truman, that the Democratic Party, led by Hubert Humphrey, made any serious official attempts to get away from the states' rights doctrine. 0Strom Thurmond lead a breakaway states' rights party after the convention. By executive order, Truman intergrated the military services. When I was in the Air Force in England in 1956, an NCO lost some strips for prejudicial conduct. Lyndon Johnson's Great Society civil rights legislation formally tied the Democratic Party to civil rights. The Great Society was, in reality, an extension of the New Deal. Johnson consciously imitated Roosevelt with domestic programs.
