The 4th District encompasses nine communities in Camden and Gloucester counties: Chesilhurst, Clementon, Gloucester Township, Laurel Springs, Lindenwold, Monroe, Pitman, Washington and Winslow.
The district leans heavily Democratic — about 44% of those who have registered to vote are Democrats, compared with about 21% Republican. Most of the rest are unaffiliated.
The 4th was a split district until the 2011 election, when its Republican assemblyman was redistricted into the neighboring 3rd District. It has been reliably blue ever since.
Democratic Sen. Fred Madden, a Washington Township man who is dean of the Gloucester County Police Academy, is facing a challenge from Republican Stephen Pakradooni Jr. of Sewell, who was an unsuccessful Assembly candidate two years ago.
Both Assembly incumbents are Democrats and they are seeking re-election. They are Paul Moriarty, a media consultant from Sewell, and Gabriela Mosquera of Blackwood. Republicans Denise Gonzalez, a Gloucester Township woman who is a former Marine and co-founder of an organization that opposes mandatory vaccinations, and Patricia Kline, an adjunct professor of business from Sewell, are opposing them. Nicholas Magner of Williamstown is the Libertarian candidate.
