Why isn't anyone listening to Julian Assange? He said that the DNC was not "hacked", but rather that the emails came from a DNC insider who was mad about what was going on.
We can believe Obama, we can believe Hillary, we can believe the FBI, we can believe the CIA, or we can believe Julian Assange. I'll take Assange any day.
Na. We can believe all of them have separate agendas, none of which are necessarily the truth. Wikileaks was intended by Assange to be an ego project to build a cult following. One should always take that into account. He focuses mainly on the US and western countries because they won't kill him and they're easy targets. Sure, they'll try to pull legal shenanigans but generally not have him shot in the back of the head or poisoned.
Obama wants to throw some roadblocks in the next President's way. From his perspective, to hopefully lessen damage to his policies by Trump and restrict Trump's options. Making him look overly friendly and/or dependent on the Russians will be effective. Hillary is exceptionally bitter at losing an election that she believes should have been her coronation, it's solely about taking any bit of revenge she can muster.
The FBI is caught politically. They let Hillary off from felony charges when most of the agents know she broke the law. But the FBI essentially deciding the elections will have consequences. Now politicians on both sides are furious at them. Republicans for the FBI playing along with the DOJ political theater of "clearing her" and Democrats for not doing a good enough of playing along. They're trying to stay in the middle of the road, which was impossible.
CIA has its own interests. I laughed at the NPR when they had General Hayden for an interview, and he claimed the CIA was not partisan and didn't play partisan politics. All agencies, and the overwhelming majority of government employees, within a hundred miles of DC play partisan politics. If they weren't interested in partisan politics, they would have wrangled a transfer to ANY other branch office or facility to get the hell away from that hive of villainy and scum. Hayden in particular is a good example. As far as I'm aware, he lied to Congress about illegal domestic surveillance in direct violation of the Constitution. Plus yanno, torture, Gitmo population, etc. Congress were complete morons when they didn't at least TRY to throw him into prison for repeatedly lying to them AND illegally monitoring them while they were investigating his crimes.
