No, he is not available for national office: NJ is currently using him. Go get your own.
More of this, please:
NJEA President Barbara Keshishian visited his office this week to apologize for a recent email sent to thousands of teachers by a union official that included a mock prayer for the governor’s death. According to [NJ Governor Chris] Christie, the conversation went something like this: He accepted her apology immediately but asked if the email sender would be fired for “doing something that monumentally stupid.” When the union chief questioned why the man should be fired, Mr. Christie promptly ended the meeting.
That’s from the WSJ’s interview with Christie, which will be refreshing reading for conservatives who may be just a little tired of situations where political rhetoric exceeds actions. In this particular case, the issue of the apology is just a vehicle for the real message: to wit, the Governor of NJ is not afraid of the teachers’ unions, so if the latter wants to win their current dispute with the former they’re going to have to fight for once. Given that support for freezing teacher pay in NJ is two-to-one in Christie’s favor, the governor is in good shape here.
