This ends speculation that he would challenge Governor Chris Christie.
Booker, long considered the Democrats’ best hope to beat Christie in 2013, could now face U.S. Senator Frank Lautenberg in a 2014 Democratic primary, although it is unclear what Lautenberg plans to do.
The decision by Booker essentially reshapes the field of Democrats who will now take a shot at the popular Republican governor. Christie’s post-Sandy polling numbers are virtually unmatched in a state with roughly 700,000 more registered Democrats than Republicans.
