TRENTON – As waterfront sycophants in search of the master’s ring descend on the Stack throne room, a source told InsiderNJ that the 33rd District senator and Union City Mayor won’t issue an endorsement in the Hoboken mayor’s race before the middle of July – if at all.

He’s tossing them all.

The source described Stack as supremely irritated over having gone out and backed the reelection of Mayor Dawn Zimmer only to have her turn around and suddenly pull the plug on those intentions.

“He feels burned,” the source said of the boss, as Hobokenites scramble to position themselves to be the favored successor to Zimmer.
