Rubio and Jindal are natural born Citizens. As is McCain, Romney, Fortuno, and Martinez.
Ted Cruz, since he was born in Canada, is not, unfortunately. Ted Cruz can still be put on the SCOTUS.
I have read that scholars conclude “natural born” meant the same as “native born” and was used interchangably.
That was written, in a study included in the Congressional Record, which stated George Romney was NOT eligible, as he was born in Mexico.
