Another SCOTUS Confirmation?

White House is making noises (from ABC) about another Supreme Court nomination, raising questions about whether or not Stevens or Ginsberg may be retiring. I don't see Ginsberg retiring under a Republican president; Stevens also isn't likely but is 87 (?) and thus may not be around much longer regardless. If either does step down, their calculus may be that a retirement with a Democratic Senate is palatable. However (and assuming there are 60 votes for cloture), with Landrieu (LA), Pryor (AR), Johnson (SD) and Baucus (MT) up for reelection (as well as Lieberman), the Republicans may just have the necessary votes. On the other side of the equation, Sununu (NH), Snowe (ME) and Smith (OR) may all be Republicans looking to display their independence and moderation. But on some level, a Bush failure here would be beneficial: bringing Democratic intransigence into focus and rallying the base, as well as acting as a proving ground for Republican presidential candidates and opening Democrats running for reelection to criticism for their actions. Anyways, losing one of those two would make a better court regardless of replacement.
