First, it actually is pretty brilliant that Christie came out using Barack Obama's standard excuse of not knowing and being misled. That's well played.Second, this is such an easy fix. Christie can turn it around quickly. He needs to follow through and see that heads roll. Then he can point out that he has actually fired people, unlike President Obama.This may be the rough and tumble of New Jersey politics, but it also comports to stereotypes of Christie as a bully and of New Jersey politics being seedy and corrupt. Taking charge and cleaning up could help Chris Christie quickly.It isn't rocket science. It is also a story that can go away quickly if Christie acts quickly.
