I unfortunately live in NJ and it is a really weird state politically. North and South Jersey are polar opposites and one would be surprised how many conservatives and even “moderate” Democrats there are but Trenton is a complete cesspool of political corruption and malfeasance. Local politics is where so many care less and where the state is being paved over politically and literally.
South Jersey has solidly Dem Burlington, Atlantic, Camden and Cumberland Counties. Only solidly Pubbie county in south Jersey is Cape May. North Jersey has solidly red Warren, Sussex, and Hunterdon counties, along with purple Morris County where I live. The divide is NOT between “North” and “South” Jersey, it is those who live farthest versus closest to the turnpike.
