Unlike anything I have heard Cruz say, Rubio has promised legalization of illegals here then securing borders that is not loyalty. I support Trump but Cruz is not on a par with Rubio. Loyalty is putting this country first not the desires of foreigners who come here illegally.
That's not his current (in English) position...!!!
Bottom line is as POTUS Rubo have no ability for legalization of illegals here, he respects the balance of power in DC...
So Congress would have to legally grant amnesty for that to happen...
