“Sioux Center is the largest city with 7,308 (2013). Chatsworth is the smallest with 80 (2013). The District entails all of Sioux County, excluding Boyden, Hospers and Matlock. The late Dwayne Alons represented District 4 until his death in November of 2014. Current Representative John Kooiker hails from the District, but is not seeking re-election in 2016. It is arguably one of the strongest Republican districts in the nation.”
