Fox is the foreign leader who has told Bush to rewrite our immigration laws. In spite of the fact that most of our legal immigrants come from Mexico --- that's not enough for Fox --- he's demanding free health care, free education, open borders, legalized status for any Mexican that wishes to come here, and Bush was down there just last week meeting with him about his demands.
If we just needed immigrants, we could get plenty from a variety of places --- lots of Haitians, lots of S. Africans, Nigerians, Asians but this deal making with Fox is about something else.
