Where now on NSA spying?

Glenn Greenwald has a great post up on where we go from here on the NSA spying business. He concludes that there is no way this Congress is going to take any affirmative steps to stop Bush and that the only way to correct the situation is to have the matter go before the Courts. He sees any amendments to the FISA act as impediments to court action and concludes the Democrats should attempt to fillibuster (if need be) any of the proposed amendments to FISA. He goes on to conclude:

What we need to do now, at least in my humble opinion, is buy time. We need to give these legal challenges a chance to proceed without being mooted by new legislation. Schumer's bill should be supported vigorously, even if its prospects for passage are slim. Attorneys General in solidly blue states should be encouraged to consider filing legal challenges similar to the one proposed by Sean Maloney. The more challenges that are filed, the better the chance that at least one of them will reach the merits. And when the administration is finally forced to make its frivolous legal arguments in front of federal judge, it's not going to be pretty.
