Why Voting Matters
In Delaware County, the people who show up to vote decide who represents everyone. The next election for Delaware County voters is Iowa's primary election on June 6, 2028; local elections can come sooner, so check your local election office. Many Delaware County jobs are in manufacturing and health care, so decisions about manufacturing jobs and health care costs hit close to home.
In the 2024 presidential election, about 10,100 ballots were cast in Delaware County, about the same as the 10,000 cast in 2020. With roughly 13,800 adults living in the county, that is around 74% of adult residents, above the statewide rate of about 65%.
That means roughly 3,640 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, Delaware County would add about 182 voices, more than enough to decide a close local race.
