Let me add to that! Cruz and the rest of the “establishment” all signed agreements but are continually breaking their agreements. Under a contractual agreement, if the other side breaks the agreement, then the agreement becomes unenforceable.
If Hillary wins the Presidency it will be the fault of the RNC\GOPe and those like Romney, Pribus, and they will pay for their treason. It will be the end of their party and foster the rise of a new party that will again be of the people and for the people.
