Huge? It's only a poll.
With New Jersey voters the way they are, a 5-point lead can very easily turn into a loss with 17% undecided.
It's huge b/c it gives momentum to Kean heading into Labor Day, and if he has momentum he could use it. The more important part than the 5 point lead is the 11 point swing from last month. Menendez is incredible danger, and Kean is definetly the favorite now.
Momentum is overrated. The people who pay attention to the polls generally aren't going to be all that swayed by "momentum" anyway. If momentum was exponential, a candidate that pulled ahead would never lose.
