I really don't know.
I mean, it's certainly possible Bush could nominate him. It's possible he could nominate nearly anyone. But I'd rather someone with credibility on record stated this. His record, so far, on Judicial appointments as been solid. I'm willing to give him benefit over doubt over WAPO's anonymous friends.
The idea that anyone connected with that fishwrap had any clue what the President's thinking is on SCOTUS nominees is laughable. I doubt anyone knows, actually. The President will have a list of names and then pick one when he needs to - not before.
