 Since then, the state has created house districts 28A (in 1996) and 26A (in 2012) as majority-minority districts.These seats have been mostly reliably blue in an otherwise sea of red outside larger cities.Since their heyday in the seventies, the South Dakota Democrats have since seen their influence decline in the state, in large part due to divisions within the state party caused by wedge issues like Roe v. Wade and the Oahe Irrigation Project.
