When he tries to deny that he was directing this at Sarah Palin, just remember that the crowd *got it immediately*. And I don't blame him for being pissed; she's the one ruining his shot at the gold, and she was definitely able to use humor and sarcasm against him as well. But, uh, real good way to win the women back, Obama - you know, all those women that were Hillary supporters, who you ignored when you went for Biden? Win them back by not-subtly calling another woman VP candidate a pig (followed immediately by a comment about the smell of fish. No, really.) (In case the reference is lost on anyone; he was, as his crowd understood, alluding to her not-that-funny joke about the difference between a pit bull and a hockey mom. I didn't think it was funny, but neither is this.)
And for more contortions on how he just *didn't mean it that way* when he so obviously did, keep this in mind (and again, the crowd certainly knew what he meant) - either he's stupid or he thinks we are.
For the record I don't think it's "sexist." I just think he's an asshole.
