Why Voting Matters
Why does voting matter in Merrimack County? Because every eligible voter here has exactly the same power at the ballot box: one vote. The next election for Merrimack County voters is New Hampshire's presidential primary, set by state law for March 14, 2028 unless the Secretary of State chooses an earlier date; local elections can come sooner, so check your local election office. With health care and retail among the county's biggest employers, issues like health care costs are decided by the officials voters choose.
Merrimack County voters cast about 92,500 ballots for president in 2024, up about 3% from 89,900 in 2020. Compared with the county's roughly 130,000 adult residents, that works out to about 71%, close to the statewide rate of about 71%.
That means roughly 37,200 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, Merrimack County would add about 1,860 voices, more than enough to decide a close local race.
Across about 933 square miles, Merrimack County averages around 169 people per square mile, mixing neighborhoods, towns and open land. About 11% of all New Hampshire residents live here.
