Who did Presidents McCain or Romney put on the Supreme Court? Who would ROMNEY name if the nation went nuts and elected him in 2016 (which I guarantee you it won't). William Kunstler is dead. ROMNEY could appoint Bill Clinton who has his law license back. ROMNEY could name Hillary or Janet "Shakes" Reno or Eric Holder? Is Lois Lerner available? Decisions, decisions!
Actually, there's no such requirement to have a law license, or even a degree of any kind, to hold a position on the USSC.
As to who Romney would nominate, it wouldn't surprise me one bit if, as a special F— You!, he nominated Obama.
