Forget who watches the watchmen, who's watching the autosign machine. So Barry was too busy hob-nobbling around Europe to sign the patriot act in person, and rather than do what ANY other person would and have it faxed to him he had an aid feed it into the same machine that signs the Whitehouse Christmas cards.
I suppose it makes a possible John Kerryese strategy of I signed the Patriot act but I never signed the Patriot act. Wouldn't you as president want to check the final version of any law you sign to make sure those dastardly republicans hadn't slipped in something you didn't like.
At the minimum this is placing way too much faith in your staff.
