If you haven't already gotten a chance, be sure to read Joan Biskupic's article on the Supreme Court  in today's USA Today, a good primer on the choice that voters face on Election Day.
The appointment of life-tenured judges can be an administration's most consequential legacy, as Obama and McCain observed in last week's debate. Five of the nine Supreme Court justices are age 70 or older, so a new president might have to make multiple appointments.
Because the court is tightly split over issues such as abortion rights, race-based policies and the handling of Guantanamo Bay detainees, even a change of one justice could alter the law across the nation for decades to come.
The article does contain one line of very generous understatement.
[Palin] has invoked God on public occasions and suggested she does not believe in a high wall to separate church and state.
I think that's a pretty safe inference.
The website also offers a fun little SCOTUS quiz . (I don't mean to brag, but I aced it.)
