Affirmative-truth bump.
It's always been a (convenient?) Bush delusion that they could pull enough of the Hispanic vote to make a difference in a general, nationwide election.
They were fooled by the not-so-subtle differences between the migrants from northern Mexico ("Nortenos") that Texas gets from nearby Mexican states, and the migrants from the Mexican interior and south who are much, much "leftier", much more PRD than PAN, and much more antagonistic toward gringos and our culture. Those are the folks who flock to L.A. and put up that repugnant monument that reads "it was better before they came" -- "they" being us, the citizens of the United States.
But for the Bushes and their audience, it was always about cheap labor anyway. Everything else was secondary at best.
