Nearly every N.J. county voted more Republican in 2024 than in 2020 and 2016. See how your county voted.

Despite losing nationwide, Vice President Kamala Harris won New Jersey in Tuesday’s presidential election, the ninth election in a row the state has voted for a Democratic candidate.
But Harris did not win a majority of support in every county, with Republican president-elect Donald Trump winning support in 12 of the state’s 21 counties. (See which candidate your county voted for in the map below).
Mercer County was the bluest in the state, giving Harris a 33-percentage point lead over Trump. Ocean County was the reddest, with a 36-percentage point advantage for Trump. Seven of the counties that voted in support of Trump also threw their support behind him in the 2020 and 2016 elections. But five counties flipped their support from Democrats in 2020, to Trump in 2024. No party flipped from Republican to Democrat between 2020 and 2024.

Statewide, Harris is on track to win New Jersey by about 6 percentage points, the smallest margin for a Democratic candidate for president since 1992. (Electoral delegates are awarded based on the overall statewide vote.) New Jersey last went red in 1988. Trump lost the state by 14 points in 2020 and 16 points in 2016.
Town-level presidential results are not yet available, with several counties waiting to release precinct level results until after results are certified. It’s likely that a number of New Jersey towns that supported Democrat Joe Biden in 2020 will have flipped their support to Trump in 2024.
Overall voter turn out is shaping up to be lower in 2024 than in 2020, with about 4% fewer ballots cast in this election. But the Democrats lost 13% of the votes they had in 2020, while Republicans gained about 6%, according to preliminary results.
Democrats still outweigh Republicans in New Jersey, with 2.5 million voters compared to the GOP’s 1.6 million. But all 21 counties saw their Republican base grow, adding more than 178,000 voters between 2020 and 2024. Democrats added less than 10,000 during that same time.
