“Why should Cruz withdraw to support any other candidate? That would be a betrayal of his ideals and his supporters.”
Depends on whether the GOPe is playing Cruz as a patsy, and if so, whether he would rather be a patsy who helps lead the GOPe the promised land of a brokered convention resulting in, say, a Romney/Ryan ticket that was guaranteed to lose to Hillary, with Barrack Hussien Obama subsequently being appointed by President Hillary Clinton to replace the late Antonin Scalia to drive the final nail in the U.S. Constitution’s coffin, such that the U.S. Constitution will thus finally be permanently relegated by the “Progressives” to its well deserved position as a historically curious piece of meaningless dusty old parchment scribbled by a bunch of irrelevant dead white men, and any rights you may formerly have enjoyed under its former protection will be gone forever.
Now THAT would be a betrayal of his ideals and his supporters!
Cruz and his wife are too smart and well-connected for that. He's no patsy -- he's all in.
Indeed it would, IF your scenario were to materialize.
