ah, but this is not a law that needs changing, it's the Librarian's opinion that needs changing. It's a ruling, not a law. Basically, Obama just told everyone to shut up and suck a lemon. If he wanted to change it, he could call the Librarian and say "Hey, I need you to change something for me", or just publish an executive order - change it or get on my kill list.

He could change it, but he's not interested enough to change it.
