This document dump will be a big nothing burger, a political farce.
WikiLeaks is doing this only because 99% of their stolen documents harm Conservatives, or harm the USA military, or harm USA intelligence gathering, or harm pro-American foreign leaders.
This dump will allegedly show that WikiLeaks is fair and balanced and attacks Socialists and America haters, too.
I don’t think wikileaks has much love for the current administration. They pretty much despise government and politicians - period. While I am sure they are far left in ideology they do not, and have not, identify with the DNC.
As others have said - to this point, they have not bluffed. They have followed through with what they have claimed even if they tease everyone with it for a month beforehand.
Part of their power is credibility. Can’t see any upside to them for promising this and not following through.
Wiki leaks is purportedly against government - to be fair, their previous releases have been damaging to the left, especially outside the U.S.
