The consensus seems to be that U.S. Solicitor General Donald Verrilli had another bad day before the Supreme Court. This time was over the constitutionality of Arizona SB1070. Or at least parts of the law.
Supporters of the Arizona law have focused on this quote by Chief Justice Roberts: "It seems to me that the federal government just doesn't want to know who is here illegally or not" as if it was some sort of revelation. Here is the dirty little secret... illegal immigration brings in money into the federal coffers while enforcement is a cost.
