Signing Statements

I have sent the following note to all three presidential campaigns. I'll let you know their answers.

"President Bush has used signing statements far more than any other president in history, and in such a way that very few people know exactly what any particular signing statement really says. It's my understanding that these signing statements will remain in effect indefinitely unless they are specifically revoked by executive order, court order, or new legislation. What will you do about President Bush's signing orders?"
