Kinda. It looks like the Dems still control things by a large margin
The Republican Party in New Jersey is practically non-existent as a political force. It's basically about as serious and effective as the board of directors for a local Elks club.
North NJ which is the populous part of the state is all Blue. Not gonna change in my lifetime.
Rs were not supposed to gain any of the NJ seats, one report in advance of the election said they would lose a few more. So, this is a nice change, four more in the Assembly takes out three incumbent Dems and brings Rs to 30 out of 80 and one more senate seat, also held by an incumbent D, which brings it to 25-15. Totally unexpected.
