Why Voting Matters

Local work in health care and restaurants and hospitality means debates over health care costs directly affect Sanders County families.

That means roughly 3,580 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, Sanders County would add about 179 voices, more than enough to decide a close local race.
