The text on the US government website from today references legislation made in 1978 (and applied retroactively) to all births after 1952. Section 301(g) of the INA states that a child in Ted Cruz's position would acquire US Citizenship from birth.
Case law that predates that legislation is irrelevant.
He acquires citizenship, yes. The question here, and the one before the court was whether said citizenship was "natural born" or naturalized.
