Why Voting Matters
Why does voting matter in Sussex County? Because every eligible voter here has exactly the same power at the ballot box: one vote. The next election for Sussex County voters is Delaware's presidential primary on April 25, 2028; local elections can come sooner, so check your local election office. With retail and manufacturing among the county's biggest employers, issues like local businesses are decided by the officials voters choose.
In the 2024 presidential election, about 148,000 ballots were cast in Sussex County, up about 14% from 129,000 in 2020. With roughly 225,000 adults living in the county, that is around 66% of adult residents, above the statewide rate of about 61%.
That means roughly 76,900 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, Sussex County would add about 3,840 voices, more than enough to decide a close local race.
