The number of undecided voters usually drops as election day gets closer, but that’s not happening this year in the big races in New Jersey.

Polls show between 10 and 15 percent of New Jersey voters are undecided on a candidate in the U.S. Senate race, and that hasn’t changed much in the past month.

Fairleigh Dickinson PublicMind Poll director Krista Jenkins says that’s because of voter perceptions about Democratic incumbent Bob Menendez and Republican challenger Joe Kyrillos.

 “Given the low identification that they seem to have with Kyrillos and also some degree of unfavorability toward Menendez it kind of puts voters in this state of some uncertainty not quite sure what to do.”

Rutgers Eagleton poll director David Redlawsk there hasn’t been much change in the number of New Jersey voters who are undecided about a Presidential candidate.

“Most voters had already made up their minds and the undecideds were no more than five or six points. When it’s that small even early on there’s not much room for it to go down.”

While it is unusual not to see a drop in the number of undecided voters, Monmouth University Polling Institute director Patrick Murray says it might not matter.

“I don’t think in New Jersey it’s going to make much of a difference just because the Democrats have such commanding leads.”
