Under Attack

Why is the Obama administration determined to do what's wrong on immigration? Votes.

The federal government has just filed suit challenging the state of Arizona’s new anti-illegal immigration law. The basis? The Supremacy Clause, which says that federal law trumps state law. But that argument should fail in a court of law because the Arizona law mimics the federal law. It basically gives the state a mechanism to enforce federal law, to turn over people police have a reasonable suspicion to believe may be illegal over to the feds.
The Supremacy Clause doesn't preclude states taking action to enforce federal law.
The Supremacy Clause only comes into play when a state law is “contrary” to a federal law or the Constitution. And courts have ruled that the states have “concurrent authority” when state law only mimics federal law. -- Five federal appeals courts have applied this in context of illegal aliens, upholding states’ rights to arrest illegals.
It sounds pretty straight forward. So why are Democrats showing Arizona so little compassion?
