A new Monmouth University poll shows Barbara Buono’s gains have been slowed by Gov. Chris Christie. The poll says that Christie is maintaining a 21 percent lead over Buono, who saw a big jump in the numbers in August. Garden State voters likely to participate in the November election give incumbent Gov. Chris Christie a 56% to 37% lead over state Sen. Barbara Buono, nearly identical to the 56% to 36% spread in Monmouth’s August poll. More than 8-in-10 likely voters say they won’t change their minds about who to support in this election.
