McCain was already winning NY, NJ, and CT
I’m aware of that. The contests were not locked up.
This endorsement - unfortunately - probably does.
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.
