NJ really isn’t deep blue. Trump lost MA, CA, NY and MD by over 20 points. Oh, and D.C. by a mere 88 points. Those are deep blue. DJT lost NJ and CT by just over 13 points, RI by under 12 points, and OR & DE by 11 +/- 0.5 pts. The GOP has decent chances to flip three House seats in the Garden state: NJ-03, NJ-05, and NJ-11.
I should have been clear that I was talking about three Trump-won districts. But another FReeper accurately pointed out that Tom Kean Jr. is running to flip NJ-07, a district Clinton won by just over a point. But Romney won it by over six points the previous election.
