This is Obama?

Perhaps this has been covered by an earlier diary, but Obama was one of the six Democrats that voted for Rice's confirmation today.

Rice, who not only proved to be utterly incompetent at her job as National Security Advisor, given that 9/11 was on her watch, is also a confirmed liar and derives an unlimited degree of arrogance from the security of her close relationship to bush.

I don't see how rewarding her with such a vote is consistent with being an aggressive reform Democrat. Perhaps someone could explain it to me?
