Chattahoochee County's electorate is shaped almost entirely by its military footprint — Fort Moore dominates the local economy and population, producing an unusually transient demographic that complicates voter registration patterns year over year.
The county's recent history is a story of close margins. The Democratic margin reached ninety-nine points in 1932; the Republican margin reached forty-eight points in 1972. Most other elections have been decided by single-digit points.
Chattahoochee County's demographics — a population of 8,887, a 58% non-Hispanic-white share, a median household income of $61,042 — situate the county close to national averages on several dimensions. The county's voting pattern over the last decade is most similar to that of Mitchell County and Conecuh County.
