Constitution of South Dakota
The Lieutenant Governor of South Dakota is the lieutenant governor of the U.S. state of South Dakota.
He or she is the second-ranking member of the executive branch of South Dakota state government and also serves as presiding officer of the South Dakota Senate. The lieutenant governor succeeds to the officer of governor if the office becomes vacant, and may also serve as acting governor if the governor is incapacitated or absent from the state.
The lieutenant governor is elected on a ticket with the governor. Seven lieutenant governors have gone on to be elected governor in their own right: Charles N. Herreid, Frank M. Byrne, Peter Norbeck, William H. McMaster, Carl Gunderson, Nils Boe and Dennis Daugaard. Two others, Harvey L. Wollman and Walter Dale Miller, succeeded to the office of governor when it became vacant, but neither won re-election.
Carole Hillard became the first woman to serve as lieutenant governor when she was elected in 1994.
