I thought this article was interesting.
The Obama administration has a lot of fights on its hands. Putting aside real wars in Afghanistan and Iraq, there's the battle against leaking oil in the Gulf, the struggle against 9.7 percent unemployment across the country, and clashes over the president's agenda on Capitol Hill. Despite all that, the White House has found time to issue a new declaration of war, this time against an unlikely enemy: the state of Arizona.
I think we are starting to see other states follow Arizona's example and the Obama administration is trying to adopt a policy of containment.
