Hancock County's mix of summer resort towns like Bar Harbor and working fishing communities along Penobscot Bay produces a Democratic lean that has held consistently, with Biden and Harris both carrying it by double digits in recent cycles.
The Democratic margin in Hancock County reached its widest at twenty points in 1912. The margin in 2024 was twelve points — still decisive.
Hancock County's loyalty is rooted in its place. Median household income of $72,744, a 93% non-Hispanic-white share, and a population of 56,460 together describe a community whose political habits are deeply settled. The county's voting pattern over the last decade is most similar to that of Knox County and Ulster County.
