Summary of the big picture.

In my opinion, this is Sundance at his (their) best. He's calling this a prequel, a recapitulation of salient events that brought us this far to Andrew McCabe being fired, promising much more to come. Reading this earlier I thought, Jeeze, this is excellent. The threads are so numerous and so intertwined and they shift over time that it's nearly impossible to keep them all straight. Yet Sundance restates all that was previously discussed in a way that makes sense. Then I noticed that Instapundit linked to the same post saying, "Here's the essential program to track the FBI scandal If you aren't reading The Last Refuge, spend 10 minutes with this and you will be henceforth and forever more." He links to this.

Excerpt:

Evidence of this laundry process is found in a significant “search query” result that was actually a mistake. The faulty intelligence mistake was the travel history of Michael Cohen, a long-time Trump lawyer. The FISA search turned up a Michael Cohen traveling to Prague. It was the wrong Michael Cohen. However, that mistaken result was passed on to Chris Steele and it made its way into the dossier. Absent of a FISA search, there’s no other way Christopher Steele could identify a random “Michael Cohen” traveling to Prague.
