As Trump's blue-state tour heads back East, it would be worth a stop in New Jersey, where he was only down 4 points in early September according to the Emerson poll.
Of course, that series also had him down only 3 in Rhode Island, which a more recent poll from Emerson shows has widened into a 20-point lead for Clinton. Something similar may have happened in New Jersey in the meantime, but unlike RI, a stop in NJ could have influence in neighboring eastern PA.
Emerson broke down support by Congressional district, and Trump's greatest margin in districts with large populations, and that are blue counties needed to flip the state, is in the 3rd district (50 to 38) and 6th district (60 to 32).
The 3rd is mainly Burlington County, which is part of the Philadelphia metro area and about 70% white. A rally here could draw people and media interest from the PA side of the Philly metro.
The 6th lies along the northern Shore and lower Gateway regions. It contains New Brunswick and Middletown. District is over 60% white. A rally in the western part of this district would draw fans from the northern red county of Morris, along with nearby red counties in Monmouth and Ocean. Unfortunately not as close to PA.
The make-up and appeal would be highly similar to eastern PA, so the same speech could be given. It's filled with groups who love Trump: white ethnic, Catholic, downsized blue-collars and a nervous suburban middle class that isn't so obsessed with liberal culture war issues, is weary of government corruption, and dreads tax increases. (Earlier post showing that the Mid-Atlantic is the most tax-hating region of the country, and has been since at least the '70s.)
At this point, there's only so much more blood that can be squeezed out of the stones that Trump has visited dozens of times already. It would be worth at least one rally in NJ during a tour of eastern PA.
Downside is a waste of a few hours of Trump's time, upside is boosting support in eastern PA to win that state, and converting NJ into a close state rather than a solid blue state (mandate). And regardless of the Electoral College outcome, a boost to the national popular vote coming from NJ.
