The Constitution says nothing about the parents... Had Marco been born in Cuba then yes he can’t run.. Did Marco go through a naturalization ceremony??
The constitution says ‘natural born Citizen’. I was very clear what that was and still is. The immigration act of 1790 made it clear that being born to two US Citizens was the key criteria and would allow one to be ‘considered as’ a natural born Citizen. Note that punctuation (no hyphen) and capitalization of the C in the act were exactly that of the Constitution. Congress wanted to drop the jus soli requirement and rely solely on jus sanguinis. So blood is thicker than dirt when it comes to being an nbC.
The situation with Rubio and Jindal, who I really like as well, is probably much more cut and dry than Obama’s.
Both of their parents were not yet US citizens at the time of there birth. So their parentage citizen status is better defined than Obama.
I think if the Obama case ever got into court on its merits they would rationalize that a US citizen mother gives him jus sanguinis. But that case can not be made for Rubio or Jindal.
