GOP voters in NJ are not very conservative to begin with, outside of the NW part of the state. This is one of the last places I know of where most Republicans who have newspaper subscriptions still read The New York Times.
I'm punching the button for Mitt next Tuesday, but know that McCain should win the Garden State by 5-8 points.
The Florida board was alive with anti McCain posts, but conservatives have been pretty much marginalized, IMO.
Good luck.
