"I am not in the habit of supporting people who attack my wife and attack my father."  What is surprising is that he said this publicly, thus further undermining his claim to acting on high principle.

Krautie has a strange definition of 'principles'.  Isn't a man standing up against attacks on his family demonstrating high principles?  If he endorsed Trump after those cowardly attacks, he's be betraying his family.  I have no interest in ever seeing Cruz as a candidate again (and likely won't), but on this matter he got it right.
