So what is more likely: that multiple (independent) intelligence agencies were somehow wrong about Russian involvement, or that an Assange (an individual who has the motivation to see Trump win, a history of Russian contacts, and a track record of dishonest behavior) would be lying about Wikileaks involvement with the Russians.
Perhaps if Assange actually provided evidence that the source was not the Russians that evidence can be judged on its merits. But at this point we have no reason to accept Assange at his word.
Assange has been quite accurate in the past with his "leaks" and posts.
I've already pointed out that the data in the wikileaks dumps was accurate. What I pointed out was that Assange,
when dealing with personal or internal Wikileaks matters, is often dishonest/untrustworthy.
Assange said he'd turn himself over if Manning was released. Manning was released. Assange has not turned himself over.
Assange told the British court system "Sure, you can let me out on bail and I won't try to avoid prosecution". Assange skipped bail to hid in the embassy.
Assange promised the Ecuadorians he wouldn't interfere with other countries while he was in residence at their embassy. He got involved with an internal spanish referendum.
Assange also: broke into rooms in the embassy that he was specifically told not to enter, and was illegally accessing staff information files.
So why would you find someone like that more trustworthy than MULTIPLE INTELLIGENCE AGENCIES (staffed by people on both sides of the political spectrum), as well as the intelligence services from other countries?
A good question might be, will Assange be arrested or pressed for evidence.
Why is that relevant to the issue about whether Assange was being honest when he said "Russia wasn't the source"?
Plenty of people lie about their involvement in crimes. Assange (wanting Wikileaks to
appear unbiased, even if he's not) has the motivation to lie about Russia being the source.
