Donald Trump heads into Tuesday’s New York GOP primary with a huge lead over rivals Ted Cruz and John Kasich — and New Yorkers lauding his brash outspokenness.

Trump is ahead in his home state with 54 percent support, followed by 21 percent for Cruz and 19 percent for Kasich, according to a new CBS News battleground tracker poll.

Trump has the potential to scoop up all of New York’s 95 delegates Tuesday if he can win the majority of the vote in each of the Empire State’s 27 congressional districts.

A candidate who scores at least 50 percent in a New York congressional district gets all three of the locale’s delegates. If a candidate places first in a district with at least 20 percent — but less than 50 percent — then he gets two of the three delegates.

The statewide winner would get New York’s remaining 14 delegates if he breaks 50 percent.

Trump also holds significant double-digit leads in California and Pennsylvania, the poll showed.

New York Republicans view Trump as effective, authentic, electable and a good negotiator, the poll found.

Notably, Empire State Republicans aren’t looking for their hometown candidate to tone down his rhetoric “because they’re New Yorkers,” Anthony Salvanto, CBS News elections director, said on “Face the Nation.”

Trump told Staten Island supporters at the Hilton Garden Inn on Sunday that he has fond memories of working summers on the island for his real-estate-magnate dad.

“I love Staten Island,” he said. “I worked on Staten Island for four summers. I love it. The greatest people.”

When asked the location of his favorite slice of pizza in the borough, Trump responded: “I have a lot of them . . . Denino’s is good.”

Trump has been winning primaries, but has struggled capturing delegates at various state conventions. Cruz has beaten him badly recently in Wyoming and Colorado.

Trump said he didn’t put in any effort there, whining that those competitions were “rigged.”

“When it’s up to the bosses — we didn’t play in Colorado, because I heard that it was going to be for the bosses, for the RNC,” he told supporters. “I’m not going to waste a lot of money.

Don’t forget, I’m self-funding. We didn’t play there, we didn’t play in Wyoming, because the game was rigged. That’s what you have to do, take them on trips, put them in hotel rooms. I don’t want to play that game.”

Later, Trump rallied supporters in Poughkeepsie, repeating familiar campaign themes about “winning” and building a wall along the US-Mexico border.

“There’s never been anything like this,” he told supporters at the Mid-Hudson Civic Center. “The movement is about winning. You’re going to go home and you’re going to remember this event. Remember they called it a phenomenon.”
