I'm not usually a huge fan of Arianna Huffington. I check out Huffington Post a couple times a week, but I don't really care what Paul Reiser has to say about 2008 election, so I don't go too far into it. Huffington is a master of the media, and she controls her image very well. I used to poo-poo self-promotion, but now I'm smarter about that stuff.
Here's a clip of Huffington on the Early Show responding to Rendell comment about Janet Napolitano not having a family and therefore able to work 24/7. Huffington's post is very sensible. Nobody, men or women, should work that many hours. The brain needs to recharge. She adds that single people have lives, too. Napolitano plays tennis and rafts.
So, Rendell's comment is sexist, only because he would never have thought to say such a thing about a man. But it is also wrong headed, because working 24/7 is just stupid and counter productive.
