Apparently Rubio’s parents became legal residents but did not get citizenship until Rubio was four.
This will lead to Democrat Birthers, which might be amusing in a primary, but Rubio can’t be president.
I see you did some further research.
I agree with your conclusion in #42.
Creepy that he didn’t acknowledge that fact when being considered for VP. If he had, I would be a huge Rubio fan. That he didn’t, tells me a great deal about Marco Rubio.
