By far, the most intriguing part of his Friday episode-and by "intriguing", I mean "self-evidently insane"-was his lengthy, twisted justification for the shots he took at Cruz's wife and father".
Trump likewise said it was "dishonorable" of Cruz to abandon his pledge to support the Republican nominee.
"He didn't ask me to endorse and, indeed, three days ago I talked on the phone with him and told him, 'I'm not going to endorse you, '" Cruz said, defending his non-endorsement speech.
"One of the best speeches - if not the best speech - tonight", said Chris Herrod, a 50-year-old delegate from Utah who had worked for Trump's vanquished rival Ted Cruz, the USA senator from Texas.
"If a convention's goal is to unite our behind one candidate, Senator Cruz didn't get the memo", fellow Texan and former Governor Rick Perry told CNN.
"Hillary Clinton's legacy does not have to be America's legacy", Trump will say. I have a message for all of you: "the crime and violence that afflicts our nation will soon come to an end", he said. Cruz is booed out of the hall even by his own Texas delegates. Predictably, his words set off alarms in European capitals and served as an unwanted reminder of his recklessness and his political bewilderment.
Although Perry had been one of the first Republicans to blast Trump early in the primary season, he's now a full-throated backer of Trump.
"Ted Cruz's decision was bold, reckless, politically stupid, brave, principled, divisive, gutsy and vindictive, all the same time", writes National Review's Jim Geraghty on Thursday morning. "It is about the United States of America".
The sense of passionate conflict among Texans Thursday was a microcosm of the friction on the convention floor Wednesday night.
Already on Friday, some Democrats were beginning to brand Trump as a would-be autocrat, because of his boast during his nomination acceptance speech that he is the only person who can lead the nation out of what he described as chaos and terror threats. The candidate has provided relatively few, and thin, policy proposals. Which could have been viewed as a nasty thing in terms of what he said because it was implying something which is wrong, but that's okay.
Although Trump tried to publicly brush off the struggle to win Cruz's support, senior Trump adviser Paul Manafort went at Cruz's pro-Constitution profile. To me, not signing a pledge is dishonorable, okay?
What is the equivalent gender-based attack on Trump to the buttons being sold outside of the arena in Cleveland that read, "KFC Hillary Special: Two fat thighs, two small breasts, left wing"? or the numerous T-shirts and bumper stickers that refer to her with a coarse synonym for a female dog? I have such great - I don't want his endorsement. just - Ted, stay home, relax, enjoy yourself. just a couple of things. He told the people to vote their conscience.
In a contest that pits two politicians viewed as unfavorable by large segments of the American people, Trump will accuse Clinton of failures while serving as President Barack Obama's first-term secretary of state and cite her use of a private email server and destruction of emails as evidence that "corruption has reached a level like never before".
