I think it is the bullshit one from the AP, which excludes at least four caucus states, includes Florida, and, if you can believe it, includes primaries that didn't count in Washington, Nebraska and several other states. I am from Washington, and I can tell you that many Obama supporters did not vote in our stupid primary. It was after the caucus and everyone knew it wouldn't count. Many didn't vote to protest the stupidity of the legislation adopting a primary when both parties were content to caucus. When I heard the AP was counting our primary (but not our caucus) I almost fell off my chair.
