Elections in South Carolina |
---|
The 1966 South Carolina United States Senate election was held on November 8, 1966 to select the U.S. Senator from the state of South Carolina simultaneously with the special election to fill out the remainder of Olin D. Johnston's term.
Incumbent Senator Strom Thurmond, who had switched parties from Democratic to Republican in 1964, easily defeated state senator Bradley Morrah in the general election. This was the first time South Carolina popularly elected a Republican senator, and the first time since 1877 that a Republican won this seat.
