Monmouth County is south across the harbor from NYC, pretty well-to-do, and the area (and Gwinnett's readership) are definitely Democrat turf. Quinnipiac is more Trenton-centric, but also a Dem-leaning poll historically (though it has delusions of impartiality and some national visibility, it has always erred on the "D" side in making calls). Judging by the sources, I'd say McCain has a great shot in Jersey. Sarah Palin will certainly resonate with the middle-class women voters of both parties there.
The more I think about it, the more I am convinced the "Uncommitted" are going to break for McCain/Palin, for the reason I stated above.
