"I actually voted for the 87 billion before I voted against it."
You take Bush's (mis)quote way, way too literally. Out of context as well, if I'm not mistaken.

If Kerry was getting as much publicity these past four years as Bush has, you'd find he would have said just as many things that can come off as stupid. If not more. If you listen to anyone for long enough you'll find a lot of things that don't make sense in what they say.
