If I were Jan Brewer or the governor of any other state that has passed an immigration law, I would go to the Pubbies in Congress and have them declare Obama's "dream decision" unconstitutional, since it was done by fiat and not through an act of Congress, which the Constituion clearly requires.
Of course, this reveals my own "dream act": Pubbies exhibiting courage!
Arrgghhh!
Imagine a President declaring that the feds would not enforce drug laws, and that the states could not arrest anybody caught transporting drugs across a state border because regulation of interstate commerce is a federal function.
