Secondly, Schwarzenegger is not an enforcer of the law. He has no constitutional authority to order the mayor of San Francisco to do anything, and despite his attempt to do so, he also has no constitutional authority to tell the Attorney-General of California to enforce the law either.

Wait, I'm confused: is the role of the executive branch in California different from the role of the executive branch everywhere else? Because unless my junior high social studies teachers were lying to me, it's precisely the role of the executive branch to enforce the laws passed by the legislative branch, or, in this case, by referendum.
