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. In 2016, Donald Trump flipped the county back to the Republican column, capturing over 56% of the county's vote, the best Republican performance in the county since the 1972 landslide victory of Richard Nixon. Trump increased his vote share to almost 60% in 2020 and increased his margin of victory to over 21%, the first election in the county decided by a margin of over 20% since 1964.
