Thanks but Cruz is not "working" establishment" rules. He's being propelled along BY the establishment which is actively helping him in order to stop Trump. Cruz isn't some delegate Svengali who is going around the establishment and beating them at their own game. He's their tool.
It is amazing all the fantasies and conspiracies that Trumpets invent about Cruz in order to justify their hate filled positions. Anything that does not support Trump, or works against his getting the nomination is attacked in the vilest way and turned into some supposed dirty trick by Cruz.
