When President Bush sits down with Mexican President Vicente Fox at the White House on Wednesday, the U.S. president will have an opportunity to shed light on the most persistently debated question of his presidency: just how compassionate is George W. Bush’s brand of conservatism? At the top of the agenda for this meeting is the formulation of U.S. policy toward more than 3 million documented and undocumented Mexicans living in this country. The leaders will discuss permanent legal status for Mexican immigrants and stronger protections for migrant workers. At stake is a better life for Mexican immigrants and their families.
