Not quite. Obama has a better claim than Rubio.
Obama had one citizen parent and one legal resident parent.
Both Rubio's parents were legal residents.
Personally, I'm a jus solis guy, so they're both NBCs in my book.
Better claim to what? You're either a U.S. citizen or you're not. Vitter notwithstanding, the 21st century interpretation of natural born citizen, as evidenced by Barack Obama, is pretty straightforward. Were you born in America?
Rubio was a U.S. citizen at the moment of his birth. Parents notwithstanding, he as an individual is no different legally than Barack Obama.
(I realize this is nothing but inflammatory, but I'm making this point for a reason. The Democrats will burst into flames if they try to attack Rubio on this. The wheels will fall off their support in Hispanic communities, and it's a monster of the Democrat's own making. The rules should naturally be more legally clarified than this, but until they are, we may as well play the game to our advantage while we can.)
Obama Sr. was never a resident alien. He was here on a student visa only.
