N.H. Republicans Expand Voter Registration Lead as Nearly 3,000 Democrats Fall Off N.H. Voter Rolls

CONCORD— New Hampshire’s latest voter registration snapshot shows Republicans widening their advantage as Democratic registrations slipped by nearly 3,000 since May, according to state data.

As of August, there are 321,650 registered Republicans and 272,316 registered Democrats, giving the GOP a 49,334-voter edge. In May, the gap stood at 48,821, meaning Republicans increased their net lead by 513 despite an overall decline in the statewide voter file.

All three major affiliations contracted from May to August, but Democrats saw the sharpest drop. Democratic registrations fell by 2,964 (about 1.1 percent), while Republicans decreased by 2,451 (about 0.8 percent). Undeclared voters—the state’s largest bloc—dipped by 2,146, from 380,695 to 378,549 (about 0.6 percent).

In total, New Hampshire’s rolls shrank by 7,561 voters, from 980,076 in May to 972,515 in August (down 0.8 percent). Even within that contraction, Republicans improved their standing relative to Democrats, translating into the 513-voter increase in the GOP’s margin.

By share of the electorate, Republicans hold about 33.1 percent of registrations, Democrats about 28.0 percent, and undeclared voters about 38.9 percent. Compared with May, Democrats’ share edged down (from 28.1 percent), Republicans held steady (33.1 percent), and undeclared voters ticked up slightly (from 38.8 percent).

The movement reflects routine list changes that occur between election cycles—such as residents moving, deaths, or voters updating their status—but the bottom line is clear: Republicans expanded their registration advantage by 513 voters, while nearly 3,000 Democrats fell off the rolls over the same period.
