The south in jersey is republican
North West as well.
Somerset/Hunterdon have traditionally been Republican. Malinowski is a first termer, and I can see him losing his seat in November.
I live in Ocean County. My wife and I and her younger sister and her brother-in-law and her sisters two daughters and their husbands are vote Republican. I used to be a Democrat. I was born and raised in Kearny, West Hudson County.
