Morrow County's sparse, ranch-and-farm landscape anchors a Republican tilt that reached 48 points in 2024, making it an outlier even within a state where rural eastern counties trend heavily red.
The unraveling was not abrupt. The Democratic margin in Morrow County peaked at forty points in 1964; it narrowed steadily over the late twentieth century. The 2000 election delivered the county to the Republican party for the first time in many years, by a margin of twenty-eight points. By 2024, the margin had widened further.
The economic and demographic context is severe. Morrow County's median household income of $75,448 is among the lowest of any county in the United States; 13% of residents live below the federal poverty line. The county's voting pattern over the last decade is most similar to that of White Pine County and Hill County.
