Hillary Clinton is one debate and a week away from a double-digit win over Bernie Sanders in the key New York Democratic primary, according to experts and new polling data released Tuesday.

A Quinnipiac University poll showed Clinton maintaining her double-digit lead over Sanders, 53 to 40 percent, among likely voters. She enjoyed a much wider lead, 65 to 28 percent, among blacks.

But Sanders could narrow her margin of victory — and even pull off an upset, however unlikely — if he keeps his base of younger supporters fired up.

“There’s a potential for him to make inroads in the debate with African-American and Latino voters in New York, which he hasn’t been able to do elsewhere. He should take on issues like race and police issues,” suggested Monmouth University pollster Patrick Murray.

Political analyst Bill Cunningham, added, “He has to hope that Hillary’s supporters look at the polls and get complacent and stay home and don’t vote. I think she and her team has to be worried that he’s a fast closer, he could be breathing down her neck.”

Thursday’s debate at the Brooklyn Navy Yard is being broadcast from 9 to 11 p.m. on CNN and NY1. It is not open to the public, with most tickets allocated to the two campaigns.
