Well we certainly know who unmasked Flynn - the list was released this week and it contains a bunch of politicians and a couple of "intel" people, which calls their motivations into question. The question of why is an important one, because of the implications of a political administration being able to wiretap its opposition, legally, based on flimsy predicate. What it should be is a valid national security concern, and by that I mean genuine evidence of corruption and/or fealty to the foreign entity. By all accounts, there was none of that in the Flynn surveillance, but rather the fact that he merely asked the Russians to not retaliate after the late term Obama sanctions were imposed until after they were in office and could take a look into it. Maybe you think that indicates a genuine national security concern, but most reasonable people would not.
So was Russia trying to "help Trump win" when they gave all that made up dirt to Steele to fuel Hillary's oppo research project? Because if you think someone in the Kremlin would do that against Putin's wishes, you really don't understand how the Kremlin works at all. So all we know for a fact is that they did some things that appeared to be pro-Trump (or anti-Hillary) but you have to evaluate their efforts in totality if you don't want to be seen as a political hack. You can look at all the "reports" you want, but as long as a major underpinning of their conclusions is that the "Russians" stole the DNC emails and provided them to Wikileaks, that story has so many holes in it that no serious person should accept their findings. We now know that, Mueller's indictments notwithstanding, there is exactly zero evidence to support that, beyond the fact that they had access to the DNC network when the emails were taken. I think if we are going to accuse a nuclear power of a crime, we should have something more to go on than (basically) guilt by association.
The "you guys did it too" defense doesn't work with me, because I voted for Clinton and did not vote for Trump. What's right is right, regardless of who is in office.
