Adams County, positioned in a primarily rural section of Illinois is culturally isolated from Chicago, and therefore more conservative than the state's northeastern corner. Quincy, the county seat, holds a high number of socially conservative Catholics and likewise is the home to the campus of Quincy University, a private Catholic liberal arts college, and the Western Catholic Union.
The county is part of the historic belt of German settlement extending into the Missouri Rhineland and because it was antagonistic to the Yankee northeast of Illinois, it voted solidly Democratic until 1892. After being a swing county in the first half of the twentieth century, Adams County has been a Republican stronghold. It last supported a Democrat for President of the United States in 1964, when it voted for (Lyndon Johnson. The county regularly rejects Democrats at the state level as well; it hasn't supported a Democrat for Governor of Illinois since Adlai Stevenson II in 1948. Notably, while it warmly supported Barack Obama in his 2004 Senate campaign, it shut Obama out in both his presidential bids.
The county is currently represented in the U.S. House of Representatives by Republican Darin LaHood. For the Illinois House of Representatives, the county is located in the 94th district and is currently represented by Republican Randy Frese. The county is located in the 47th district of the Illinois Senate, and is currently represented by Republican Jil Tracy.
