Orleans County, anchored by the small city of Newport on Lake Memphremagog, has shifted from reliably Democratic territory to a near-even split, mirroring rural Vermont's broader realignment along education and economic lines.
The county's recent history is a story of close margins. The Democratic margin reached twenty-eight points in 2008; the Republican margin reached seventy-six points in 1904. Most other elections have been decided by single-digit points.
Orleans County's demographics — a population of 27,606, a 94% non-Hispanic-white share, a median household income of $70,103 — 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 Winona County and Rutland County.
