NH Republicans Expand Registration Lead as Democrats Post Sharpest Drop in Voter Rolls

CONCORD, NH — New Hampshire Democrats, already the smallest of the state’s major political groups, have seen their ranks shrink faster than anyone else — a troubling sign in a state where even a handful of votes can swing major outcomes.

According to data released yesterday from the Secretary of State’s Office, Democratic registration fell from 272,316 on August 5 to 268,067 on November 3, 2025 — a loss of 4,249 voters, or 1.6%. Republicans saw a smaller decline, down 3,948 voters (a 1.2% decrease) to 317,702 total. Undeclared voters — the state’s largest bloc — dipped slightly by 3,556 (just 0.9%) to 374,993.

The numbers mean there are now nearly 50,000 more Republicans than Democrats registered across New Hampshire. That growing gap could have real implications: in 2022, control of the 400-member New Hampshire House was decided by just 11 votes statewide, underscoring how tight the margins can be.

While all voter groups saw modest declines this fall, Democrats lost the most both in raw numbers and percentage terms — despite starting from the smallest base. Political observers say that points to an enthusiasm problem within the party as voters increasingly drift away or disengage.

By contrast, Republicans have maintained a steadier footing and now enjoy a sizable registration advantage heading into the 2026 elections. For Democrats, reversing that trend will be critical in a state where — as recent history shows — a difference of just a few votes can decide the direction of government.
