Montgomery County's large active-duty and veteran population tied to Fort Campbell gives it an unusually transient demographic mix, yet it has delivered Republican presidential margins consistently above 15 points across recent cycles.
The shift began with civil rights. 2000 marked the realignment in Montgomery County, by a two points margin. The Republican margin reached its widest at eighteen points in 2016. The 2024 margin was eighteen points.
The political shift has tracked, in Montgomery County, the political shift of the South more broadly. A 63% non-Hispanic-white share, a median household income of $75,613, and a 11% poverty rate describe the demographic context. The county's voting pattern over the last decade is most similar to that of Lancaster County and Screven County.
