Obviously, Ted Cruz is *not* a “natural born citizen” of the United States.
A natural born citizen has been construed to mean born to at least one parent who is a U.S. citizen regardless of what soil he was on at birth. Here, it is alleged Cruz's mother, Eleanor, is a U.S. citizen by birth. This could very well mean Cruz is a natural born citizen. (Same could be true of Obama if his mother was in fact a U.S. citizen at the time of his birth. Why he evaded (and continues to evade) the issue is another story.)
