Greene County's 2024 margin of R+57.8 places it among Illinois's most heavily Republican counties, a stark contrast to the Democratic strongholds that dominate the state's overall electoral math. Its population has declined steadily for decades alongside the contraction of small-scale agriculture.
The unraveling was not abrupt. The Democratic margin peaked at thirty-seven points in 1932 and narrowed across the late twentieth century. The 2000 election carried the county to the Republican party for the first time in many years, by eleven points. Between 2020 and 2024 the county moved three points toward the Republican candidate; the 2024 margin was fifty-eight points.
The economic context is severe: a median household income of $62,192 — among the lowest at this geographic scale — and a 14% poverty rate. The county's voting pattern over the last decade is most similar to that of Pike County and Linn County.
