Why Voting Matters
Why does voting matter in San Juan County? Because every eligible voter here has exactly the same power at the ballot box: one vote. The next election for San Juan 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 San Juan County jobs are in restaurants and hospitality and arts and recreation, so decisions about tourism and small businesses and parks and tourism hit close to home.

That means roughly 139 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, San Juan County would add about 7 voices, more than enough to decide a close local race.
