More about the item below. Here's a Josh Marshall 2004 item with the following quote:
RUSSERT: Were you favor of the war in Vietnam?
BUSH: I supported my government. I did. And would have gone had my unit been called up, by the way.
RUSSERT: But you didn't volunteer or enlist to go.
BUSH: No, I didn't. You're right.
The paper-work shows that Bush checked off the box that says "do not volunteer" when he signed up for the National Guard. Maybe he changed his mind. Ask Fred.
