New Jersey gained 2,492 Democrats and 1,402 Republicans during the month of November, ending a recent trend of Republican voter registration gains in a state that elected a Democratic governor, Mikie Sherrill, by fifteen points on November 4.
Republicans added 46,166 new registrants to the voter rolls since the November 2024 general election, while Democrats lost 5,579. In total, New Jersey added 9,722 new voters last month, but lost 85,376 voters since the ’24 election.
The state has 854,554 more Democrats than Republicans – a massive advantage, but still down from the one-million edge it had in 2020. The number began to decrease after Democrat Joe Biden defeated Republican Donald Trump later that year.
New Jersey has not elected a Republican governor in twelve years and has not elected a Democrat to the U.S. Senate since 1972. Democrats have controlled the State Assembly since 2002 and the State Senate since 2004; from 2002 to 2004, the upper house had 20 Democrats and 20 Republicans, leading to shared control of the Senate.
In the 7th congressional district — one of the most competitive in the nation – there are now 20,524 more Republicans than Democrats. That’s up marginally from 19,849 after the 2025 election.
The state’s electorate is 38.1% Democratic, 25.2% Republican, and 35.6% unaffiliated (also known as independents).
The Natural Law Party gained 322 new voters since November 2024, even though the party has been defunct for over two decades.
