Well, no real surprise here. President Obama has thrown a sop to his far-left buddies by selecting Sonia Sotomayor, the farthest-left of the various judges whose names had been bruited about as nominees to replace retiring Supreme Court Justice David Souter, as his pick. Sotomayor has a reputation as a hard-left ideologue. My guess is that he picked her because Rosa Luxemburg was already dead.
And while Obama said that he didn't have any particular prerequisites in terms of demographic groups, he did indeed pick a woman, (and a minority woman at that) as was predicted. Perhaps he thinks she's the best qualified person for the job, the brightest legal mind in the country; but perhaps she's just another affirmative action pick. When it comes to the Supreme Court, people who are appointed for life, being selected because you're a woman is just as offensive as not being selected because you're a woman.
