What New Jersey needs is a judiciary whose judges are willing to take principled stands and defend the system of separation of powers and the rule of law. Resisting political pressure is a necessary part of the task. A judge who is worried about being reappointed is simply not putting the law first.
Two wrongs don't make a right. Governor Christie may be entitled to choose his judges (as are our Presidents) but any choice of a judge based on the outcomes of cases yet to be decided, and not on principles and a respect for procedure and the law, is sure to be flawed. Whether one agrees or disagrees with Christie's choice or rationale, the sitting members of the New Jersey judiciary should not be protesting if they are not reappointed. The very concept of "appointment" means that judges should not be expecting to remain, as if if were some sort of entitlement or de facto lifetime-tenured position.
