Left Coast Rebel points out that two thirds of Americans can't name a single Supreme Court Justice.
I'd like to turn this issue on its head and ask why should the whims of Justices be so important in our lives that we should need to know their names. The Constitution set out rights of individuals and restrictions on the powers of government to meddle in our lives. I think the founders would be horrified to learn that Washington power is so all-encompassing in our daily lives that we follow every Presidential and Congressional election and every Supreme Court nomination as if our livelihoods depend on them (which they do, in Obama Nation, of course!).
