//Cruz, for good or ill, EARNED his speaking slot.//
Yet the nominee has a lot of pull. Remember how Ron Paul wasn’t allowed to speak unless they proofed is speech (ie endorsed Romney)?
Trump could have not let him speak, but by letting Cruz hang himself, Trump showed himself to be gracious and took away Cruz’s platform.
Trump heaped hot coals on Cruz’s head. It was Cruz’s choice whether to make that into a cook stove or a funeral pyre.
Romney was and is a RINO and a detestable person. And Cruz earned a whole lot more support in the primaries than Ron Paul did. He earned that spot on the podium.
He didn't have to perform seppuku, though. That's all on him. And it was utterly stupid.
