Union County, N.J. has some conservative havens:
Westfield
Cranford
Summit
Springfield
NJ is nothing like PA... all states have the blue vs red in the urban vs rural.. the problem wth NJ is its a relatively small geographical footprint with two HUGE urban centers in it.. the NYC burbs and the Philly burbs... not enough land mass and population to counter the urban D vote unless the D’s anger too much of the middle.
Too much geographical footprint of NJ is blue to even remotely compare it to PA.
Christie is leaving office at nearly single digit approval ratings, no R has a shot at a win in that environment.
