Obama campaign's predictive internal memo: where can I find it?

Apparently a while ago someone in the Obama campaign leaked an internal document that was printed in January and showed their prediction for how the race would play out, which was accurate in predicting the outcomes of a bunch of the upcoming contests.

I’ve searched for this document and though I can find references to it, I’ve been unable to find the document itself. I’d be interested to read it and to know whether this streak of prediction has continued. Is it available anywhere?
