What makes you think Bush opposes the SC ruling.
That is my concern. Silence reveals much.
A better question is, what makes people think Bush CAN do anything? He can't use executive order to overturn a judgement, that's against the rules too, separation of powers. Only a higher court can do that. What he CAN do is order a constitutional amendment strengthening the intended wording, but still that will not overturn the judgement made, and the people who lost out because of it.
