New Jersey Gov. Chris Christie has called for a special election to fill the Senate seat left vacant by Democratic Sen. Frank Lautenberg, who died of pneumonia Monday. The primary will be August 13, and the general election, October 16. In the meantime, Christie, a Republican, will name a place holder to the seat, but he says he hasn’t decided whom yet. "I do have a preference for one party over another, so that may color my judgment a little," Christie said when asked about the temporary appointment. Christie is up for reelection in November.
