President Bush stands nearly alone in Washington. He hasn't the backing of the Congress, the press, at least half of the dim bulb public, many members of his own party, a good chunk of talk radio (including Levin and Linbaugh who are more interested in proving how much smarter they are than Bush).
The President has done the best he could with the situation he was handed in November. I really don't care if you would have felt better if we took it to the Supreme Court and lost; that would have cost us more than a lost court case, and I am sure you will agree when you think about it.
even if we had lost the court case, the wiretaps would have reverted to where it is now (after this decision) - with FISA. the outcome would have been the same.
