Politics

Douglas is a strongly Republican county. Apart from a narrow plurality of thirty-two votes to Bill Clinton in 1992, it has voted Republican in every Presidential election since 1968, and in all but five overall since 1880. Despite its long-time Republican leanings, Hillary Clinton's 2016 performance of gaining a mere 23.8 percent of the county's vote stands over six percent worse than any Democrat since the Civil War.
