The SCOTUS Justices was touched on in another thread. Seven of the present Nine have been appointed by Republicans. Only Ruth Bader Ginsburg and Stephen Breyer were appointed by Clinton.
Everyone is pulling for McCain, but his willingness to embrace the dark side in the spirit of "bipartisanship" leads me to believe no matter who wins the election, SCOTUS Justices will list heavily to port just to get past confirmation.
As for the term limits for SCOTUS justices, it was envisioned that way to give the Court a steady more consistent hand in interpretation of the Constitution and we see how that is working out. Just to throw another grenade in the fire, there is no limit on the number of Justices either. FDR was rebuffed, but there is no Constitutional construct for the number of justices.
