The mainstream media buzz appears to favor Edith Clement, possibly because she is not seen as a threat to that most sacred of liberal sacred cows:
Known as a conservative and a strict constructionist in legal circles, Clement also has eased fears among abortion-rights advocates. She has stated that the Supreme Court "has clearly held that the right to privacy guaranteed by the Constitution includes the right to have an abortion" and that "the law is settled in that regard."IMO, this means she's not a "strict constructionist", regardless of how she's known in legal circles.
UPDATE: The president will announce his nominee at 9:00 eastern time tonight. He's asked the networks to cover the announcement.
