UPDATE: via the WashingtonPost.com
With 98 percent of the vote counted, Clinton led with 51 percent to 45 percent for Obama (Ill.). Former senator John Edwards trailed far behind with four percent. However, although Clinton captured the popular vote, Obama edged her out for delegates at stake, taking 13 to her 12, according to an Associated Presss analysis.
I told you caucuses were weird.
