The 2017 New Jersey Gubernatorial Election, a Contest between then Former Ambassador to Germany Phil Murphy, and then Incumbent Lieutenant Governor Kim Guadagno is one which will probably be one of the Last hurrahs for the Old NJ Coalitions
More working Class than previous NJ Coalitions, Phil Murphy ended up doing better than Hillary in the southern White Working Class counties of Camden Atlantic, Gloucester, Salem, Cumberland and Cape May, in addition to the Minority Heavy counties of Essex and Hudson.
However, Murphy Underperformed Clinton's Numbers from the Year before in the Suburban Counties of Somerset Hunterdon, Morris, Middlesex, Union, Mercer and Monmouth, showing aspects of the old GOP Suburban Coalition.
Looking at the Congressional District map, a Similar pattern Opens up with Murphy winning the working class 2nd Congressional District(Van Drew) while losing the suburban seventh congressional District (Malinowski).
However, the 5th(Gottheimer) and the 11th(Sherrill), both Suburban Seats Swung Towards Gov. Murphy between 2016 & 2017.
*Note: The lower "(R) 4-6%" Should be "(R) 2-4%"
However, most of that swing can be atribbuted to a combination of a) the northern suburbs being pissed at Guadagno for being associated with Christie and Bridgegate, and b) Sussex County Taking a Hard Left Turn from Trump's High the previous year(In addition to NY Expats migrating to the county)
Lastly, Taking a look at the Legislative District Results, Murphy Ended up winning 39 Legislative Districts as seen on the left, and he inproved most in the Working Class/Southern LDs, Northernmost urban LDs and The Lakewood District(thanks to the town of Lakewood NJ), in addition to running around even to 2-4 points ahead of Clinton in the Burlington, Passaic, & Bergen suburbs
All In all, it will be interesting to see what Murphy's New Coalition in 2021 will become, so as to see how much support he gains or loses in the North and South, and more specifically how close can he get to his 2017 Essex and Hudson Numbers
