I'll wade briefly into primary-related commentary to say that as in Iowa, Obama pulled off the feat of actually getting a lot of people to the polls. It's a bit weird to judge a candidate by the success of his campaign. I mean, obviously, in some sense that's how all candidates are judged, but part of Obama's spiel is that he's so awesome that he'll get lots and lots of people to come out to vote for him.
The press is overplaying the race and gender stuff, with a little help from the campaigns themselves of course, though that isn't to say there's nothing there. But I agree with Digby that it's the younger people that provide the more interesting story.
