Jersey County's federal political history is fairly typical of “anti-Yankee” Southern Illinois counties.{{Citation needed|date=November 2022}} It voted solidly Democratic until [[Warren G. Harding]] carried the county in his record 1920 landslide. It voted Republican again in [[Herbert Hoover]]'s landslide of 1928, but otherwise was firmly Democratic until [[World War II]], when opposition to US involvement turned the county to [[Wendell Willkie]] and then [[Thomas E. Dewey]]. Between 1948 and 2004, Jersey County became something of a [[bellwether]] county, voting for every winning presidential candidate except in the Catholicism-influenced 1960 election, and that of 1988 which was heavily influenced by [[1988–89 North American drought|a major Midwestern drought]]. Disagreement with the Democratic Party's liberal views on social issues since the 1990s has caused a powerful swing back to the Republicans in the past quarter-century.<ref>Cohn, Nate; [https://www.nytimes.com/2014/04/24/upshot/southern-whites-loyalty-to-gop-nearing-that-of-blacks-to-democrats.html ‘Demographic Shift: Southern Whites’ Loyalty to G.O.P. Nearing That of Blacks to Democrats’], ''[[New York Times]]'', April 24, 2014</ref> As is typical of the [[Upland South]], [[Hillary Clinton]] in 2016 did far worse than any previous Democrat, while [[Joe Biden]] performed marginally better in the 2020 election.{{Citation needed|date=November 2022}}
