You think the establishment really wants Cruz as the nominee? They're supporting him now because he's the only vehicle they can use to stop Trump from hitting 1237. Make no mistake, if there is no majority on the first ballot, there will be more candidates than Trump and Cruz and they will probably take it from both of them.
Only chance is if Cruz somehow leads Trump in delegates prior to the first ballot and even then I doubt it.
I gotta agree with JRoby. The
only reason Cruz is getting support is that he's the anti-Trump. If he somehow comes away with the nomination, the GOP goes down in flames in November.
