Why Voting Matters
Voting is how Knox County residents shape the decisions made in their name. The next election for Knox County voters is Maine's presidential primary on March 7, 2028, though a statewide referendum could come first on November 2, 2027 if any question qualifies; local elections can come sooner, so check your local election office. Local work in health care and retail means debates over health care costs directly affect Knox County families.
About 25,900 people voted for president in Knox County in 2024 (about the same as the 25,700 cast in 2020). That equals roughly 75% of the county's estimated 34,300 adults, above the statewide rate of about 72%.
Around 8,430 adults here did not vote for president. Some aren't eligible, yet the rest are untapped power: one more voter in every 20 of them would mean about 421 extra Knox County ballots, enough to change the result in many close contests.
