Adams County, positioned in a primarily
rural section of
Illinois, is somewhat more
conservative than the state's northeastern corner. President
Donald J. Trump set the record for highest percentage of the vote ever received in 2024, vacuuming in 73%. Trump also previously set the record in 2020, and in 2016. Quincy, the county seat, is home to 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. Since 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 has gone Republican in all but four presidential elections since 1920, all but one of which was a 400-vote Democratic landslide. The county last supported a Democrat in 1964, when it voted for
Lyndon Johnson. The county regularly supports the Republicans at the state level as well; it has not supported a Democrat for Governor of Illinois since
Adlai Stevenson II in 1948. Additionally, five of the six countywide elected officials in Adams County are Republicans, with a Democrat holding the position of Circuit Clerk. Notably, while it voted for
Barack Obama in his 2004 Senate campaign, he lost it by wide margins in both of his presidential bids. The county is part of
Illinois's 15th congressional district, currently represented by Republican
Mary Miller. For the
Illinois House of Representatives, the county is located in the 94th district, represented by Republican
Randy Frese. The county is located in the 47th district of the
Illinois Senate, represented by Republican
Jil Tracy. ==Education==
