By any fair analysis Ted Cruz is “man enough.”
You will find little fair analysis, unfortunately.
The quality of Levin's analysis must be considered and judged in the context that he is a polemicist. Even so, I think his analysis most of the time is reasonably fair and indisputably well grounded in the Constitution and recent history.
I do fault him for his churlish behavior with callers who disagree with him. In my judgment he loses credibility every time he demeans a caller. But even this fault demonstrates his conservative bona fides which is really the issue that was raised.
Just as Mark Levin must be made wrong for Trump to the right so must Mark Levin's conservatism be attacked to make Donald Trump acceptable.
