Any child born outside the limits of the U.S. derives their US citizenship through “derivative naturalization”.
Ted Cruz is a naturalized citizen.
Ted Cruz relies on 8USC1401(g) for US citizenship to run for US President, but 8USC1452(a) says that makes him a derived naturalized citizen, and thus he is Article 2 ineligible for the US Presidency. Arguments relying on statute lose, because only amendments change the US Constitution.
SCOTUS opinion in Rogers vs Bellei 1971 overruled District Court and will deny Cruz the Presidency, while Luria vs US 1913 will guarantee him all 14A rights, privileges and immunities, except serving in the Presidency.
Ted Cruz is a naturalized citizen.
You don't have to convince me. I figured this out years ago.
My rule of thumb is this: If you wouldn't be considered a "natural born citizen" by the laws in effect in 1787, then you are not one now.
If it requires a subsequent law to make you a citizen, you are not a "natural" citizen.
