He served as a delegate to the
1940 and
1944 Republican National Conventions. From 1959 to 1963 he served as a state Senator and in 1960 he was appointed by Governor
Ralph Herseth as a member of the Dakota Centennial Commission. He is best known for winning, without any opposition, the 1960 South Dakota presidential primary and did not run in any other state. Lloyd, alongside that year's Republican nominee,
Vice President Richard Nixon, and
Governor of West Virginia Cecil H. Underwood (who also ran only in his home state), were the only candidates to win primaries in 1960. In March 1969, he died in hospital in Yankton, South Dakota at the age of 83. He had suffered a stroke two weeks earlier. ==Electoral history==
