Leelanau's blend of resort tourism, cherry farming, and an educated in-migrant population produces Democratic margins unusual for rural Michigan, where most similar counties trend sharply the other way.
The Democratic margin in Leelanau County has rarely exceeded eight points in modern history; the Republican margin has rarely exceeded sixty-seven points. 2024 delivered the county to the Democratic candidate by eight points.
Leelanau County's demographics resemble the country more than they resemble most counties. A 90% non-Hispanic-white share, a 7% poverty rate, and a median household income of $99,422 — all within the broad national range. The county's voting pattern over the last decade is most similar to that of Kent County and McLean County.
