For most of its history, Scott County was primarily a Republican county. From 1880 to 1984, it only supported a Democrat for president nine times, six of which were national Democratic landslides. In more recent elections, the county has become consistently Democratic in presidential elections like many other midsize urban counties nationwide, with the party's candidates winning the county in every presidential election from 1988 on. However, their margins of victory have not been as wide as in many other counties of similar composition, especially in 2016 when Hillary Clinton only won the county by 1,291 votes.
