Allow me to educate you. Here is a New York Times study of college football allegiance by zip code:

Hoboken's zip code is 07030. The breakdown for the zipcode in their study is 12% PSU, 10% RU, 6% ND. So yes, according to the most reliable data set we have on the matter, there are more PSU fans in Hoboken than Rutgers fans.
Looking at New Jersey as a whole, PSU owns the state with the exception of the area directly surrounding Rutgers. As much as this message board echo chambers likes to pretend there is widespread support for the university in every corner of the state - it is just simple false.
Let me educate you - your "study" was based off Facebook Likes. Not very scientific...
And PSU owns NJ? Yea okayyyyyy.
