Early voting is underway in New Jersey as the November presidential election approaches, with at least 1.45 million people casting ballots in person or by mail starting Thursday.

While we won’t know the results of how residents across the state voted until after the polls close on November 5, we can look back at detailed data from past elections.

Democrat Hillary Clinton won New Jersey from Donald Trump by more than 540,000 votes in 2016, taking home 256 cities.

In 2020, Democrat Joe Biden won by a margin of 700,000 votes, gaining a majority in 310 New Jersey cities. (See the city maps of both election years below.)

An overwhelming 88% of New Jersey cities voted for the same party in both elections.

Between 2016 and 2020, 67 cities flipped, election data show. Of those, 60 switched from Republican in 2016 to Democrat in 2020.

Polling stations will remain open for early voting until Sunday. Your local early voting location may not be the same as your polling place on Election Day, so be sure to check before you head out.

Republican Donald Trump will be on the ballot for the third presidential election, while Democrat Kamala Harris will top her party’s list for the first time. Voters will also make their voices heard in local elections, including city council and school board races.

Statewide, Democrats in New Jersey still have an advantage among registered voters, but their lead is shrinking.

In 2020, there were 1 million more registered Democrats than Republicans. From September 2024, that benefit will have fallen to 920,000. The deadline to register to vote in Tuesday’s election was October 15.

The total number of voters has remained stable over the past four years, growing only 2%.
