Lord, please let nothing happen to any of the fab four.
That's one reason that the SC nominations were not that big of an issue for me in this campaign.
Would I rather have had McCain making the selections than Obama? Sure.
But, the oldest justices are the most liberal. Chances are that any retirements will simply replace one liberal with another.
Except for the fact that Obama has learned one thing from recent Republican appointees - put them in young, in their fifties at the oldest. That way they can stay for a good 25 years. I would rather have the liberals at 88 and 75 than 50 and 55 (Roberts' and Alito's ages at appointment).
