The NJ Republicans won the gerrymander for the Congressional redistricting as a result of the 2010 Census. Unfortunately, the NJ Democrat's map won for the legislature.
Lonegan's 44-55 loss (with 6277/6330 precincts) is actually better than almost every poll. Plus he was outspent 10-1. If the Republican Party had actually put some effort into this, who knows?
2. I don't think the national GOP will ever take New Jersey seriously in a U.S. Senate race. Heck, the Democrats don't really take these races seriously outside New Jersey, either.
