Politics

Jasper is politically a fairly typical "anti-Yankee" Southern Illinois county. Opposition to the "Yankee" Republican Party and that party's Civil War meant that Jasper County voted solidly Democratic until isolationist sentiment drove its voters to Warren G. Harding in 1920.

Since the New Deal, the county has shown a steady trend away from the Democratic Party due to major shifts in that party's views – initially on economic policies and since the 1990s on social issues.[27] Only one Democrat, Lyndon Johnson, has won a majority since 1940 in his 1964 landslide. It appears to be a statistical change in the Upland South, that Barack Obama in 2012 and Hillary Clinton in 2016 did not fare as well as previous Democratic candidates for president.
