I am totally fascinated to see if that happens, and I very much expect it to. Cruz is a dingbat who the GOP establishment loathes. What I see happening is that a ‘safe’ moderate like Rubio (who is NOT A MODERATE, but acts like one) or, lordy, Bush, will get the nomination, Trump goes third party, and we get a new ultra-right-wing super-racist party to compete with the R’s for the next few years.
But I would clap my hands with glee to see Bernie debating Trump.
