Bush once again has the Democrats discombobulated. They are almost forced to support his nomination of Harriet Miers to the Supreme Court despite her pro-life opinions and strong evangelical faith. They know so little about her that they can still plausibly hope that she might not be as "bad" as Clarence Thomas or Antonin Scalia. Should she fail to be confirmed, however, whoever is nominated in her place is most likely going to be a Thomas/Scalia clone, and it will be much harder to defeat a second nominee. Miers is about the closest thing to what the Dems want that they're likely to get, and they'll almost have to see her confirmed or face a far tougher fight over a more obviously qualified substitute.
If Miers really is a conservative and an intelligent strict constructionist, and if that's truly what the President wanted on the Court, then he is indeed a wizard at political strategy. He gets (ex hypothesi) a qualified originalist on the Bench by forcing the Dems to vote for her and without having to fight them for their vote.
Hugh Hewitt linked to someone today who recalls the words of Sun Tzu:
I think Sun Tzu would admire the Miers gambit.
