When we say President Bush, we refer to his whole administration. The President has the final decision in each issue and in each matter, but he doesn't do all the research, nor even most of it. How many people work in this administration? 10,000? 20,000? How many are working on the war? 1000?
There are other things happening. Bush has a new man at NASA, and I would bet that if O'Keefe directed one of the hordes of federal lawyers to look into property rights in space a report would be forthcoming. There might even be an EO for Bush to sign that would create an office similar to the old Land Office. Space Lands Office. File your claim at the SLO. Being bureaucratic it might well be slow.
