Why not Hillary, if she wants the gig ? She is smart..a hard worker and has been a good soldier for the Administration despite some rough treatment during the 2008 campaign. She has earned it.
Also, Hillary, through her years as First Lady, a US Senator and Secretary of State (plus all that work for the Rose Law Firm) has a different perspective on things than just someone hanging out in academia and the federal appeals courts.
And she is readily confirmable. As a former Senator, the bit of comity left in that body would help her.
It's the President's call and the Senate is still 59-41 Democrat. So you are going to get a left leaning justice. No point arguing that. I just think she would fit the bill at this time.
Unless Hillary wants to pick up the pieces in 2012 should President Obama's numbers continue to sink.
