Wikileaks has always been political.
If someone leaked the rnc's emails, those would probably be out too.
Let's not forget Cablegate in 2010.
I walked around in Philadelphia talking with DNC protestors, during the DNC. Most of them were democrats, who were glad to have evidence of corruption and collusion between the DNC and Media. Most of the protesters I talked with, only had good things to say about wikileaks, and assange.
I think wikileaks knows what they are doing, and are gaining mindshare among the alternative left and right.
