The area east of the Missouri River (or "East River"), is generally more moderate, with views that are more in line with those found in its Midwestern neighbors, Iowa and Minnesota. "West River" is more conservative, with views that are generally more in line with those found in its western neighbors, Montana and Wyoming. Large exceptions exist to the East River-West River political generalizations, however. The strongest Democratic counties in the state are West River. These counties are located within Indian Reservations. The strongest Republican counties are located East River. These counties were primarily settled by Protestant Germans from Russia, and be they Mennonite, Lutheran, Baptist or Reformed, they vote overwhelmingly Republican.
