My only concern with Cruz is his attitude toward the illegals. If he is not ready to remove them then the effect of a Cruz presidency will be different from a Clinton presidency only in that the Total Democrat State will come in all its fulness about 4 years later than it would under Mrs. Bill.
I'm not sure what Cruz plans to do about that, but it is a big question, and I do not think anyone can articulate a detailed solution without being ripped apart by the media. Better to keep the issues simpler and fewer. I'm confident that Cruz will take border control seriously and at the very least not make it easier for criminals to stay here. How much effort he puts into getting rid of the ones we have may be decided by other demands on his time, but I don't believe he will support any form of Amnesty.
