The short list may be getting shorter, but the long list is only getting longer. As President Obama continues his secretive vetting of potential SCOTUS nominees, legal scholars and media observers are throwing out even more possibilities. These may not be household names, but they offer qualities currently lacking on the high court -- or so the arguments go.

The National Law Journal's Marcia Coyle sought out more than a dozen Supreme Court and constitutional law experts to get their take on whom Obama should nominate. While nearly all agreed it would be a good idea for the president to pick a woman or minority, they also suggested some "off-the-grid" white male candidates.

After the jump is an addendum to our "long list" including these contenders as well as several dark horses named in an NPR story this weekend. Click here for the full list. Know someone who has been rumored as a possible candidate but who's not on this list? E-mail Amy Harder.
