In its early days, Lawrence County was a Democratic-leaning swing county, voting Republican only twice up to 1892 when it supported Ulysses S. Grant in 1872 and Benjamin Harrison in 1888. It did not vote for a losing Republican candidate until Wendell Willkie carried the county in 1940 due to isolationist sentiment. Since that time, however, Lawrence County – like so many in Southern Illinois – has become powerfully Republican due to opposition to Democratic Party social liberalism. The only Democrat to gain an absolute majority in the county since 1936 has been Lyndon Johnson in 1964, although Bill Clinton obtained  pluralities in both 1992 and 1996.
