Are you surrounded by Democrats or Republicans? How N.J. breaks red and blue in all 21 counties. – NJ.com

Sure, it took a day for the race to be officially called. But Gov. Phil Murphy succeeded in being the first New Jersey Democratic governor since 1977 to win a second term with his victory over Republican Jack Ciattarelli last November.

Yes, New Jersey Democrats can boast about having more than 1 million registered people in their party compared to Republicans (2,508,001 Dems versus 1,488,424 GOPers), according to the June statistics from the states Division of Elections.

But Democrats may have some reason to be concerned ahead of the upcoming midterm elections that extend beyond President Joe Bidens lackluster approval rating and a long history of voters ousting the party in control of Congress two years after a presidential election.

As voters will head to the polls Tuesday to vote in the Democratic and Republican primaries, the latests stats show New Jersey Republicans added 25,025 people to their party compared to this time last year, while Democrats shed 44,982 registered voters. Republicans also added more voters than Democrats the previous year.

There are also 2,355,148 unaffiliated voters, which is 74,410 fewer compared to this time last year.

People who have not formally claimed any party affiliation had long been the largest number of New Jersey voters. But they ceded ground to Democrats about three years ago. There are also 81,129 voters who claimed affiliation to other political parties such as the Libertarian, Conservative and Green parties.

New Jersey had more than 6.5 million registered voters as of June, nearly 100,000 fewer compared to last year.

Here is a county-by-county breakdown of which political party rules in each of New Jerseys 21 counties and how much each party gained since this time last year.

Below that is an added bonus: How each congressional district breaks red and blue after redistricting.
