If I recall correctly, you’re not even allowed to make a campaign call on a government phone, so since virtually everything George W. Bush will be doing for the next two months is campaigning is it illegal, or even an ethics violation, for him to travel on government aircraft?
It seems to me that it should be, since he will be using government resources to campaign it is at least the ethical equivalent of making a call.
If I’m wrong on this, this will be a good opportunity for me to learn, because I simply don’t have any idea.
