I wish I could have even an ounce of optimism about what this is going to do to the Supreme Court.
But I can tell you already what's going to happen*. Bush will nominate someone so extreme he makes Pat Robertson look like a commie, then use the threat of nomination #2 as leverage to ram Roberts through as a "centrist."
Then he can retreat to someone merely as evil as Roberts after the inevitable filibuster, and point to Roberts' confirmation as precedent to get the Senate to punt nominee #3 through.
Result: A sickening wide-right judicial swing, ensuring that the negative consequences of the Bush presidency are going to be with us far beyond the Iraq war.
So ... yeah.
* I really, REALLY would love to be wrong about this. But I have yet to once overestimate Bush's unfailing determination to do whatever it takes to get his way, to reward his sycophants, and to promote his ideology (in roughly that order), no matter how badly it fucks over the nation he's supposed to lead. If this doesn't end up producing a court ready to overturn Roe and ram through 5-4 decisions even worse, I will very, very gladly link back to this post and eat crow.
