Trump will take Cape May, Cumberland and Salem Counties. Possibly Atlantic county, probably Ocean, possibly Monmouth. If he takes Gloucester or Burlington that would be good but kind of doubtful. Camden is lost forever as is Mercer, Middlesex, Union, Essex, Hudson. Trump will take Hunterdon, Warren and Sussex in the North. Possibly Morris and Somerset, maybe Passaic (if Paterson turnout is low). He also has a shot in Bergen but it is not a great shot.
And with all that, he will get 35% of the votes in NJ, worse than G. W. Bush.
