PIERRE, S.D. (KELO) — Whether by mail or in person, South Dakota voters have important choices to make in the primary elections on Tuesday, June 2, including choosing nominees in 28 contests for seats in the Legislature.

Republican voters have 10 Senate primaries and 16 House primaries to decide, with contests in 18 of the 35 legislative districts. Democratic voters have two House primaries to decide.

All 105 seats in the Legislature come up for election every two years. Republicans currently hold 30 seats in the Senate and 59 seats in the House. Democrats hold five Senate seats and 11 House seats.

Republicans have already won nine Senate seats because they don’t have opponents. They are Brock Greenfield of Clark, V.J. Smith of Brookings, Jack Kolbeck of Sioux Falls, Jim Bolin of Canton, Kyle Schoenfish of Scotland, Joshua Klumb of Mitchell, David Wheeler of Huron, Mary Duvall of Pierre, and Ryan Maher of Isabel.
