I had to take a quick look at Barbara Bush's memoir when I saw this story. The Bush, Sr. family had a housekeeper come from Mexico to live with them in the 1960s through the 80s, I think. Her name was Paula, and she also was considered "part of the family."
So, with Dubya following the family pattern, it's hard to say how much this influences policy. Ideally, it should not.
