In its early days Johnson County, being strongly Southern in its culture, was fiercely Democratic. In fact, in the1860 presidential election, the county gave Illinois native and Northern DemocratStephen A. Douglas a higher proportion of its votes than any other county in the United States.[citation needed]
However, during the Civil War, under the influence of CongressmanJohn Logan, this region of dubious initial loyalty was to provide a number ofUnion soldiers rivaled on a per capita basis only by a few fiercely Unionist counties inAppalachia.[26][27] This level of Union service has meant that despite its historic hostility towards Yankee culture, Johnson County has been powerfully Republican ever since the Civil War.[citation needed] Douglas in 1860 remains the last Democrat to win a majority of the county's vote: the solitary Democratic victory since was whenBill Clinton won a plurality against RepublicanGeorge H. W. Bush and independentRoss Perot.
