This is a great map, but....................
The map is INCORRECT when it comes to Bergen County. There are no conservatives here anymore and this is NOT Christie-Country. Of the seven voting districts, 5 are chock-full of left-leaning Democrats. Obama was the favorable winner in his election here a few years ago and Christie actually LOST in this county.
PS - Bergen has just under a million people now, the most densely populated of all in the state.
