Confirm Them, one of the top blogs specializing in judicial appointments, speculates that the nominee to replace Sandra Day O'Connor will surprise everyone (except those who have read their post or who read the journal First Things).
Confirm Them says that they think the pick will be Mary Ann Glendon of Harvard Law. Glendon would be a great selection except she's 66 yrs old and may not have the longevity on the Court that most conservatives are hoping the next Justice will have.
Even so, it'd be fun to see how the Democrats handle a Glendon nomination, and it'd be very interesting to see how the Jim Wallis wing of the Christian left would react to it.
