The latest gubernatorial poll shows a tightening race between the two New Jersey candidates.
FDU Poll conducted the survey between July 17–23, to gauge feelings about the race from 806 likely voters in the state. Respondents favored Democratic candidate Mikie Sherrill in the November election to succeed Gov. Phil Murphy over Republican Jack Ciattarelli by a margin of 45% to 37%. Undecided represented 16%.
That represents a much slimmer margin than the first post-primary poll. Released by Rutgers-Eagleton earlier this month, that feedback from 621 New Jersey adults had Sherrill at 51% and Ciattarelli at 31%, with 5% going for neither or someone else, and 13% unsure.

“Unless something goes horribly awry, partisans are going to vote for their party’s candidate,” said Cassino. “While Republicans have been narrowing the gap, there are still more Democrats than Republicans in the state, and Ciattarelli needs to start pulling in more independents and Democrats if he wants to win.”
The poll also tried an experiment. After asking respondents which candidate they would support, it then randomly assigned them a series of questions about local issues, such as energy and NJ Transit, or about national issues, like President Donald Trump or immigration policies. The survey then asked respondents about their preference in the race.
“There’s a reason why Ciattarelli is focusing so much on local issues, and trying not to talk about President Trump,” said Cassino. “The more nationalized this race is, the worse Ciattarelli does overall, even as it helps him a bit among Republicans.”

Cassino said that the Ciattarelli is walking a fine line with Trump.
“He needs to consolidate Trump supporters, but do so without making the race too national, or turning off voters who don’t what’s happening in Washington,” said Cassino. “For Sherrill, on the other hand, there’s no downside to bashing Trump as much as she likes.
