Latest rumors and other uncomfirmed reports (here and here) are turning to Judge Samuel Alito as the next SCOTUS nominee. Either Alito or Judge Michael Luttig would be fine. Erick's post over at Red State is the first I had heard of the concerns that Luttig might "grow" on the SCOTUS.
Patterico on why Sen. Arlen Specter may not like Judge Alito.
Another Patterico post here, dealing with Alito's dissent in Planned Parenthood v. Casey.
