Booker already has the endorsement of George Norcross, a southern New Jersey Democratic powerbroker. So it wouldn't be surprising for other leaders in the region to give him their support during Wednesday's news conference in Deptford.

But it remains unclear if Democratic leaders in south Jersey would mobilize their extensive get-out-the-vote operations on Booker's behalf in the special election.

Booker is the early favorite in the Aug. 13 Democratic primary to fill the remainder of the late Frank Lautenberg's tem. The general election is Oct. 16, just three weeks before the gubernatorial and legislative elections.
