Take what Thought Criminal said here (no, go read it first; I'll wait. Done? Good.), add this:
“We have not drawn any evidentiary connection to any Russian intelligence service and WikiLeaks — none,” said one U.S. official. Doing so will be a challenge, in part because the material may not have been passed electronically.
Also unclear, the officials said, is the motivation, even if Russia is behind the leak. It may be that the Kremlin wishes to disrupt and discredit the U.S. political process without seeking any particular result.
Michael V. Hayden, former CIA director, said, “Frankly, I don’t think they’re motivated by thinking they can affect the election itself.” He said the Russians, already masters at “information dominance” or using information as a political and military weapon, may be flexing their muscles “to demonstrate that they can — not necessarily to make Trump win or Hillary lose.”
If they are truly behind the email dump, he said, “they’re taking their game to another level.”
The email dump, current and former national security officials said, is highly troubling, regardless of its provenance. And it could warrant considering whether the elements of the electoral process should be raised to the level of “critical infrastructure,” such as power grids and key financial systems, which merit special protection from cyberattacks, some officials said.
“We’re not used to thinking of the election system as a critical infrastructure,” said one senior administration official. “But I could make the case that it ought to be considered that. We ought to start talking about that.”
Whoever shared the emails with WikiLeaks, the senior administration official said, “sure as hell didn’t do that for our benefit.”
Yeah; this is serious. Not exactly a fit subject for sarcasm from a major Presidential candidate.
