Who Should Be Next on the US Supreme Court?

When retiring Supreme Court Justice Sandra Day O'Connor heard she would be replaced by John Roberts, she deemed him "good in every way except that he's not a woman." Justice Ruth Bader Ginsburg says she is "lonely" among her eight male colleagues. David Souter's resignation gives President Obama his first chance to nominate a Supreme Court justice, and he wants, "excellence," "integrity" and "empathy." Does "empathy" mean that he wants a woman, and if so, why? Conservatives fear he wants a justice who legislates from the bench. Should the next justice be liberal or conservative? Is there any such thing as non-ideological? Is it time for the first Hispanic? Whoever Obama's choice might be will Republicans just say "no?"
