Typically for German-settled western Central Illinois, Cass County opposed the Civil War and became solidly Democratic for the next six decades. Only hatred of Woodrow Wilson’s policies towards Germany following World War I drove the county into Republican hands in the 1920 landslide. Between 1924 and 2008, the county was something of a bellwether, missing the national winner only in the very close 1960 election and the heavily drought- and farm crisis-influenced election of 1988. In the 2010s, the county has become powerfully Republican due to opposition to the Democratic Party's social liberalism.
Cass County is located in Illinois's 18th Congressional District and is currently represented by Republican Davin LaHood. For the Illinois House of Representatives, the county is located in the 93rd district and is currently represented by Republican Norine Hammond. The county is located in the 47th district of the Illinois Senate, and is currently represented by Republican Jil Tracy.
