Arizona's recently passed immigration legislation may prove unconstitutional since it intrudes on the national government's authority over immigration matter. There are also questions about whether its enforcement will lead to racial profiling, which could violate the equal protection clause. There are arguments that it is constitutional however, including this one from the law's author. Challenges have already begun, though as with similar challenges to health care legislation, it is unclear that anyone has standing to sue yet.
Regardless, a small majority of people who have heard of the law, like it.
David Broder thinks the passage of this law adds to the argument that Congress is broken.
