The most plausible theory is these Guccifer 2 leaks not necessarily were damaging but were leaked on purpose by the DNC with fake Russian meta tags so as to use as evidence before a wire tap judge to tap Trump.
Whomever tried the translation from English to Russian screwed-up several times....... and this is how they were outed.
==========================================
Trace all of it back to the Obama paranoia---if Hillary lost, all of them would have big Big problems.
REFERENCE---Then-Pres Obama and his minions started developing the “Russian hacked the election” narrative to give them cover for their blatantly illegal spying on the Trump campaign....... Obama spying on Trump started a year earlier. This is the stuff of third-rate banana republics. Susan Rice, and all concerned, including BO, should be in prison right this minute. (hat tip Junk Silver)
============================================
FROM ONE OF THE MANY EXPOSES---Seeking to retain his position as CIA director under Hillary, Obama-era Brennan at the CIA used phony foreign intel as a pretext for a multi-agency investigation into Trump.....that led the FBI to probe a computer server connected to Trump Tower and gave cover to Susan Rice's sifting operations....
Not only Brennan.... "Susan The Sifter" had a dog in this hunt......Hillary tapped her for Secy of State. One could conclude Comey also had his reasons .....to stay on as FBI director.
Mighty powerful incentives for anti-Trump shenanigans.
.......apparently there are records proving that Obama's CIA director, John Brennan, oversaw repeated spying on the phone calls of President Donald Trump and millions of other private American citizens. An audiotape just released by Federal Judge G. Murray Snow is part of a civil case........
It just stands to reason since the other two big leaks were inside jobs via thump drive.
