In the real world Rubio was born in Miami, Florida and is a natural born US citizen. Period.
And despite Rubio's suggesting that he won't accept the VP job, I think that was just to tamp down the buzz about him. It is very likely he will be offered the slot almost no matter who wins our nomination.

It is NOT enough just to be born here. You have to be born here of parents who are citizens
So, the children of illegal aliens OR children of British citizens (Obama) are not Natural Born Citizens even if they were Native Born.
