Did Kean carry the district?
Well, it's impossible to come up with Kean's totals in NJ-07 without doing a lot of research into individual precincts in Linden (a tiny sliver), Union Township (about half), Bridgewater (again, about half), Woodbridge (almost all), and Edison (about a third), all of which are only partially in the CD.
But, if you'll allow me to use a shortcut: I totalled all the Kean/Menendez votes in the towns that are definitely in CD7 (which accounts for the vast majority of votes anyway), and then used the Ferguson/Stender numbers for the five towns which are partially in the district. [The numbers seem to be consistent with Kean/Menendez's overall performances in the towns, which bodes well for the assumption.]
From this analysis, I get Kean 53% (103,895), Menendez 47% (92,314). That's a big enough spread to safely say that yes, Kean did win NJ-07, and almost certainly by a larger margin than Ferguson did (mostly because Kean outpaced Ferguson in the towns in Stender's Legislative District).
