Most great individuals have flopped, perhaps several times, and then become successes.
Obama became a great success (for many), and now has completely flopped.
Rafael Edward Cruz has shown great promise, but is still in the indeterminate stage. It is conceivable that he might do a far greater service by thoroughly securing his senate seat and exerting influence there, than bywasting his resources in a presidential campaign.
As far as raising a loyal family without shame, apparently Romney has done that, though I do not like his religion or politics.
You do not yet know what forms of compromises Cruz would make to remain as Senator or to become President. But there will be many in a political arena that has become crassly corrupted. But in one he already seems to have--that of inherently not being a natural-born citizen, AFIK?
(Just my opinion. You don't have to loke it. It's still somewhat of a free country.)

So why bring up war records and children that have nothing to do with his promise or qualifications for being a President of the USA. As far as I am concerned he is the most articulate of all potential Presidential candidates, Republicans and Democrats. Whether he gets the nomination or not remains to be seen. He will have to earn his way. One thing certain is he is scaring some people because he is already being subjected to smear tactics.
