In interviews Thursday morning with delegates who were on the floor and other New Yorkers who were elsewhere in the arena, a story emerges of an organic uprising - one that the New Yorkers are still proud to have started, given what they see as the ghastly betrayal that Cruz perpetrated on the stage in front of them.
"We're writing his political obituary-he's dead", Stephen Bannon, executive chairman of Breitbart News, the influential right-wing website that was an early fan of Cruz, said about the Texas senator. Instead, he tried to remold Cruz's non-endorsement into an endorsement. "This is the worst possible thing he could have done".
But he also made clear it was intensely personal after a brutal primary campaign where Trump dismissed him as "Lyin' Ted", mocked Cruz's wife's looks and linked Cruz's father to the assassination of President John F. Kennedy. "He will fight for equal pay for equal work, and I will fight for this right alongside of him".
"I have made billions of dollars in business making deals - now I'm going to make our country rich again", he said. Donald Trump can't even accurately quote the National Enquirer.
He said: "Our convention occurs at a moment of crisis for our nation".
There's certainly overwhelming support for Trump at the convention.
On Wednesday, leading Republicans filling out the primetime lineup sent mixed messages to delegates and television viewers alike.
As the last speaker at the gathering, Trump, 70, has a chance on Thursday night (Friday NZT) to end on a positive note when he makes a prime-time address to formally accept the presidential nomination. "The time for fighting each other is over", the senator from Florida said, ticking off the fundamental policy differences between Trump on one hand and Clinton/Obama on the other.
Ivanka missed her one chance to date to vote for her father: she had not changed her party registration from Democrat to Republican in time to cast a ballot in the April 19 NY primary election. But on Thursday the Texan met anger and denunciations from many sides and was even heckled at a breakfast meeting of his own Texas delegation where a vocal minority of the large crowd was furious. Security escorted his wife, Heidi, out of the arena after the speech, CNN reported.
Trump and his campaign minions did everything but accuse Cruz of hating puppies. He now trails the former secretary of state in most opinion polls and needs the lift a candidate traditionally gets from the pre-election party convention.
Steve Lonegan, who ran Cruz's New Jersey presidential campaign, defended the Texan's refusal to back the nominee.
Commentators suggested the ill-timed spat might damage Cruz's long-standing dream of becoming president.
"I love the media", Trump joked. "I don't think I'd advise my kid to get involved in it", he said. He predicted a "disaster" if Trump became the party's nominee.
According to a leaked draft speech transcript published by the website Politico.com, Trump seldom went off script and when he did, he often repeated what he had just said and added an exclamation point. In a speech that positioned Trump as the voice for the voiceless, Trump drowned out Cruz's contentious call for conservatives to "vote your conscience". "Vote for candidates up and down the ticket who you trust to defend our freedom and to be faithful to the Constitution".
