Presidential Signing Statements

So in the aftermath of Shrubs first veto in his entire presidency(and people thought he was all about the power of the executive:->) Many people are now starting to realize hey President Bush has put all these signing statements on practically each bill he has signed. These signing statements essentially say I am not going to follow this part of the law. Now Al Franken has been going on about this for a while. My question is why has no one else until this moment. These signing statements are clearly an attempt by this less than brilliant President's smart advisors to gain more power for the executive branch. Historically this simply spits in the face of the constitution. What to do. We need to show how the GOP leadership allowed this to happen. Until it became aware that this president had no idea what he was doing too many in congress were simply too willing to allow their rights to be taken away. Why I will have to think on that one.
