Supreme Court Affirmative Action?

I've heard a few opinions that Harriet Miers was chosen despite her unstellar qualifications for "affirmative action" reasons. That is, Bush wanted a woman to fill a woman's seat (or, if you want to say that Roberts is replacing O'Connor and Miers replacing Rehnquist, to maintain the current gender balance).

Of course, that doesn't explain why he didn't find a woman with better qualifications, such as, say, Edith Jones or Priscilla Owen.

To the extent that this was an affirmative action decision, all that it means is that Bush picked an unqualified female crony rather than an unqualified male crony.

That is all.
