Well, here we go. Hate to say I said so... but...
Look: One of the risks of sitting on your dry powder until the last minute is that you get flanked and taken out before you can deploy your payload.
Assange is apparently on the ropes. He has no 'net, and may be under arrest for all we know. If his surrogates having key pieces can assemble and decode, they can dump the entire insurance cache under a deadman's scheme, but its more likely the spooks know who each person with a key piece is and will move to lock them down in the short term. Also, almost a certainty that cache in a "full dump" release (i.e., as opposed to the curated and indexed releases we saw last week) will have information that can compromise human assets, meaning those people getting burned would be the story regardless of whatever anti-Hillary stuff is out there. WikiLeaks took huge flack for that with the Iraq cables, so they've been trying to be better. If they have a total dump now, the story won't be about Hillary.
Drip drop didn't turn out so well for WikiLeaks.
So does OKeefe actually have shit? Will we see? If I were him, and actually had shit I would get it out the door. Playing timing games and he may end up under arrest with his computers seized, etc.
