Saratoga County's blend of historic horse-racing resort towns and fast-growing Albany exurbs has compressed a once-reliable Republican advantage to under two points in recent presidential cycles.
The county's recent history is a story of close margins. The Democratic margin reached thirty-seven points in 1964; the Republican margin reached fifty-five points in 1956. Most other elections have been decided by single-digit points.
Saratoga County's demographics — a population of 238,284, a 88% non-Hispanic-white share, a median household income of $100,787 — 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 Kent County and Dutchess County.
