CLEVELAND – Newt Gingrich bashed fellow Republicans who failed to show up at the GOP convention as sore losers.

“Jeb Bush lost, so the family doesn’t want to show up,” Gingrich told reporters after speaking to the New York GOP delegation breakfast. Asked about the other high-profile no-shows Mitt Romney, George Pataki and John Kasich, Gingrich said they just can’t handle defeat.

“I’ve never seen so many bad losers,” he said.

Trump campaign chief Paul Manafort also criticized Kasich, the Ohio governor, for announcing he wouldn’t be at his home state convention.

“You know what, he’s making a big mistake,” Manafort said on MSNBC’s “Morning Joe” program.. “He’s hurting his state and embarrassing his state, frankly. But most of the Republicans who aren’t coming are people who have been part of the past. And people who are part of the future of the Republican Party are, frankly, going to be here participating in the program.”

Gingrich was the opening speaker at the New York GOP breakfast Monday despite some initial resistance over scheduling, as first reported by The Post. He spoke for about 18 minutes to much applause on how Trump is an unconventional candidate who is poised for an unconventional win.

“Donald Trump is the grizzly bear in The Revenant,” Gingrich said, adding that he’ll get your attention, bite your head off and then sit on you for awhile.

Gingrich challenged GOP delegates to not write off New York City as a Democratic stronghold, but push to make inroads with all communities by challenging their status quo.

“Do not assume anyone is happy where they are,” he said.

“They’re not happy—I don’t care if it’s African-Americans in parts of Manhattan, I don’t care if it’s Latinos in Queens, I don’t care what group you’re talking about. It starts with the city, because if you break the city, you own the state.”

While law an order may turn the tide of the election, Gingrich also preached understanding for others.

“No white American understands the pressure of being an African American,” Gingrich said.

Gingrich was passed over by Trump for vice president, but said he’s OK with Indiana Gov. Mike Pence as the running mate.

“I had a very long talk with Donald before – two and half hours –before he made the decision,” he told reporters afterwards. “I agree with him entirely. Given what he needs to get done, Mike Pence actually would do much more to unify the party than I would.”

As for his role a Trump Administration, Gingrich said: “I’ll have plenty of access.”
