Why Voting Matters
Voting is how Washington County residents shape the decisions made in their name. The next election for Washington County voters is Colorado's 2028 presidential primary, on a date the governor will set no later than March 21, 2028, though a statewide ballot issue could come first on November 2, 2027; local elections can come sooner, so check your local election office. Many Washington County jobs are in manufacturing and retail, so decisions about manufacturing jobs and local businesses hit close to home.
In the 2024 presidential election, about 2,810 ballots were cast in Washington County, down about 7% from 3,010 in 2020. With roughly 3,770 adults living in the county, that is around 74% of adult residents, above the statewide rate of about 68%.
That means roughly 963 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, Washington County would add about 48 voices, more than enough to decide a close local race.
Covering about 2,518 square miles with roughly 1.9 people per square mile, Washington County is the kind of rural community where a few dozen votes can settle a local election.
