I know Trump hadn't never heard it or read it, or if he did never seriously thought about it, but somebody better read Ronald Reagan's 1964 Time for Choosing speech to him.
Reagan spent the speech explaining the crossroads America was on. We could take the path to a bigger progressive liberal government or the path of Conservatism and a bright future for America, and that you the voter had a CHOICE.
The last lines wraps it up pretty good and agrees with everything Cruz suggested.
You and I have a rendezvous with destiny. We will keep in mind and remember that Barry Goldwater has faith in us. He has faith that you and I have the ability and the dignity and the right to make our own decisions and determine our own destiny. Ronald Reagan
Trump on the other hand sounding like a true progressive must not think we have the ability and the dignity and the right and the right to make our own decisions and determine our own destiny.
