Leatherman was in his 11th term and among the longest-serving lawmakers in South Carolina’s Legislature. First elected to the Senate in 1980 as a Democrat, he later ran unsuccessfully for governor before switching parties in the 1990s, one of a number of lawmakers who did so as Republicans gained dozens of seats in Congress.
Leatherman soon assumed the chairmanship of the Senate Finance Committee, and in a state where the governor has less control, Leatherman was long considered South Carolina’s most powerful politician for his dominance over the state budget.
Leatherman also sat on a number of fiscal oversight boards, including the State Fiscal Accountability Authority and the Joint Bond Review Committee. A new port terminal in Charleston bears his name.
