Why Voting Matters
In Custer County, the people who show up to vote decide who represents everyone. The next election for Custer County voters is Oklahoma's special election on April 6, 2027, scheduled to include a statewide question on a constitutional convention, though a court challenge could change that; local elections can come sooner, so check your local election office. Local work in retail and health care means debates over local businesses directly affect Custer County families.
In the 2024 presidential election, about 10,200 ballots were cast in Custer County, down about 5% from 10,700 in 2020. With roughly 21,500 adults living in the county, that is around 47% of adult residents, close to the statewide rate of about 50%.
That means roughly 11,300 adult residents did not cast a presidential ballot. Some are not eligible, but many are, and that is a lot of untapped power. If just one in 20 of them voted, Custer County would add about 566 voices, more than enough to decide a close local race.
