Wait... Yahoo via AP reports that Obama's ahead of Clinton by various margins in the superdelegate count, as does MSNBC (AP), Fox News, Real Clear Politics, and The Politico.

Obama overtakes lead in superdelegates for first time - Yahoo! News
Obama Takes Superdelegate Lead for the First Time - America’s Election HQ
RealClearPolitics - 2008 Elections - Democratic Delegate Count
Obama grabs superdelegate lead - Mike Allen and Avi Zenilman - Politico.com
AP: Obama takes superdelegate lead - Decision '08 - MSNBC.com

Wall Street Journal has Clinton ahead, but by only one-half of a vote.

While it's odd that different sources are providing slightly different numbers on something that I think should be uniform, the delegate scorecard, it has been a very good week for Sen. Obama regardless.
