After voting for the Democratic nominee in its first two elections in 1848 and 1852 prior to the founding of the Republican Party, Jones County thereafter leaned Republican until 1988. It voted Democrat only four times between 1856 and 1984, in 1912 for Woodrow Wilson when he won with a plurality of the vote after former Republican Theodore Roosevelt ran as the Progressive candidate, leading to a fracture in the national Republican Party, then backing Franklin D. Roosevelt in his two landslide victories of 1932 and 1936, and then supporting Lyndon B. Johnson during his 1964 landslide. From 1988 to 2012, Jones County favored the Democratic nominee in each election.
