I'm not convinced WikiLeaks desires a Trump presidency. In fact, I'm almost certain they don't like the idea, but I'm pretty darn sure Julian Assange will not have a Clinton presidency. Full stop. and since it's Julian's baby, they'll try to engineer this with an out for the DNC.
As for Wiki/DNC, every day of leaks is just more toothpaste out of the tube.
Even if the leaks stopped tomorrow, enough hints have been dropped to point some bright young things from our side in the right investigative direction, with/without JA's help.
If he's angling for a pardon out of all this, gotta give the guy credit for cojones.
