“Really, I expected a few Cruz holdouts on the convention floor last night,” Scarborough said Friday on MSNBC’s “Morning Joe.”

“There were none."

"He had no defenders anywhere out there," he continued. “People in the Texas delegation, members of Congress from Texas, they were embittered by his showboating and coming to the convention and not endorsing.”

Scarborough also said Cruz severely hurt his chances if he runs for the presidency in 2020.

“When you have a Republican Party that was 85 percent united behind Donald Trump, it’ll probably be 90 percent united behind Donald Trump after this week and next week, he’s microtargeting in a way that does not allow him to win a Republican nomination four years from now. He’s offended the overwhelming majority.”

Cruz on Wednesday declined to endorse Trump for president in his speech to the Republican National Convention in Cleveland, instead urging Americans to vote their conscience.

Attendees began booing Cruz loudly when it became clear he wouldn't formally back Trump.

Cruz defended his decision on Thursday before delegates from Texas, saying it was personal and citing Trump's insults toward his wife, Heidi Cruz. Trump also suggested the senator's father, Rafael Cruz, was involved with the assassination of President Kennedy.

But Scarborough said Cruz shouldn't have come to Cleveland if he still had issues with Trump.

“If you’re that offended by what Donald Trump said about your wife and your father, and everybody would understand that, don’t come to Donald Trump’s coronation,” he said. "It’s pretty unbelievable.”

Scarborough also said Cruz’s decision reinforces the perception that he is loathed by his colleagues in Congress.

“I talked to a lot of members of Congress who basically said, ‘The world got to see what we’ve been dealing with for three years,’ ” he said. "It was very harsh language.

“What I heard over and over again was a lot like that from members of Congress, who said, ‘Well, everybody else knows why we hate him so much.' "
