If Cruz was truly the principled conservative, he would put principle over pride and gracefully bow out and live to fight another day. Maybe not now especially since he may do well in Utah, but if he doesn’t, and gets beat soundly in AZ he should. The math just doesn’t work for him going forward to the northeast.
He will be in long enough to block Trump’s majority. Then - SHOCK - he will recognize the futility of his path. Eventually, he will come to be associated solely with his being a tool of the GOP bosses misdeeds and never be heard from again.
