New Jersey’s voter rolls grew by 6,314 in March, largely fueled by the continued increase of unaffiliated voters, according to state data.
For the past several years, the GOP has been chipping away at the Democratic registration advantage, but its progress has stalled in recent months. Democrats added 329 voters in March, compared to just 37 for Republicans. Meanwhile, there are 5,840 more unaffiliated voters.
In the 7th congressional district, where a handful of Democrats are competing for the chance to take on Rep. Tom Kean Jr. (R-Westfield), a little more than 700 voters were added to the rolls, including 470 new Democrats, 176 new Republicans, and 32 new unaffiliated voters. Republicans still maintain an advantage over Democrats in the district — 217,146 to 197,322 — but the more than 213,000 unaffiliated voters will help decide this highly watched race.
In the 11th congressional district, where voters will pick a replacement for now-Gov. Mikie Sherrill later this month, Democrats added 49 registrants and Republicans lost 234; the number of unaffiliated voters in the 11th grew by 612 in March. Democrat Analilia Mejia is heavily favored to beat Republican Joe Hathaway in the April 16 special election. Voter registration for that race closed on March 26.
Voter registration trends don’t directly correlate to election results. Republicans tacked on voters throughout 2025, yet Democrat Mikie Sherrill still won a landslide gubernatorial victory come November.
The Garden State now stands at 6,671,137 registered voters; 38.0% Democratic, 35.8% unaffiliated, and 25.1% Republican. A sliver of the state’s voters belong to minor parties, several of which are defunct or effectively defunct.
