NJ is an affluent state with an abundance of jobs in R&D and in Finance. It is also a state where high school kids are among the top performing in the country. It also has a significant number of older urban centers that were once successful cities. Another state that could be described similarly is MA.
Since Governor Christie was elected in 2009, you can think of these two states as if they were testing the republican and the Democratic economic solutions. From two sources, here are the unemployment rates.
December 2009 (a month after Christie was elected - as a baseline): NJ - 10.0 MA - 9.3
December 2010 : : NJ - 9.1 MA - 8.2
May 2011: : NJ- 9.4 MA - 7.6
If you look at NY, also run by a Democratic governor, the results look like MA's. What is clear is that the cuts that Christie forced through have hurt the state of NJ.
