The 1902 South Carolina United States Senate election was a Democratic Party primary election held on August 26, 1902, and September 9 to select the U.S. Senator from the state of South Carolina. Prior to the ratification of the 17th Amendment to the United States Constitution, U.S. Senators were elected by the state legislature and not through the direct election by the people of the state. However, the Democratic Party of South Carolina organized primary elections for the U.S. Senate beginning in 1896 and the General Assembly would confirm the choice of the Democratic voters. Tillmanite Democrat Asbury Latimer won the Democratic primary and was elected by the General Assembly for a six-year term.
In the special election of 1897, the Conservatives were without a candidate so in 1902 four candidates vied for the support of Conservatives: Dan S. Henderson, William Elliott, George Johnstone and John J. Hemphill. The two remaining candidates in the race, Representative Asbury Latimer and former Governor John Gary Evans, were strong Tillmanites. However, they held strongly opposing views and a duel almost ensued between the two while campaigning at St. George on July 12. A fight did indeed break out between Latimer and Hemphill when they were campaigning in Gaffney on August 14. Latimer took offence to an accusation by Hemphill and struck him. Hemphill was unable to strike back because Latimer quickly left the scene.
