IF Scalia were to step down. Scalia is the 3rd oldest, I thought he was older. He could choose to retire to prevent any chance of a rat naming his successor post 2008. In fact, it might be the safe conservative thing to do.
I been thinking the same thing about Scalia. We are just one heart attack or tragic car accident of the Court being in trouble. If we dont keep the Presedency we might be in trouble. Right now we are just replacing Conservatives really.
