I'm going to break the rules for a standard "What Digby Said" post by actually adding a couple things. First, go read her eviscerate the notion that Bush was sailing in popularity until God Himself smote him with Katrina, forgetting the little matter of Terri Schiavo.
Back? Ok, check out Bush's comprehensive approval chart:
It isn't a coincidence that Bush's disapproval rating shot past his approval rating for the first time at the end of Q1 in 2005. The Act for the relief of the parents of Theresa Marie Schiavo was passed on a special session of Congress on March 20th, a Sunday and Bush actually interrupted one of his many vacations to fly to DC and sign the bill just after 1am on Monday morning. He even stayed up past his bedtime.
