They will never be a natural constituency for the GOP. Why do they keep saying that?
Wishful thinking, desperation, and political correctness, that's why.
Only a deluded fool could really believe that a group of people characterized by low income, low levels of education/skills, and a culture of dependency (on welfare, "bilingual" education programs, and affirmative action) will magically become GOP voters if only Republicans embraced amnesty and open borders.
Repeating mantras about "natural conservatives" doesn't make these PC delusions any more real.
