The Jim Wells County Democratic Party has maintained its influence in the county despite massive demographic changes due to civil rights, the collapse of Jim Crow and poll taxes, and mass immigration from Mexico.[10] The only Republicans to win the county in presidential elections since its creation are Dwight D. Eisenhower in 1956, Richard Nixon in his 1972 landslide and Donald Trump in 2020. Since 2004, Jim Wells County has become slightly less Democratic than it was during the late twentieth century.
