Who knows how they came of it. I expect we're doing the exact same thing to Russia, gathering dirt on them. I expect if/when the time comes that Putin is vulnerable, we'll be going to his detractors (hopefully better concealed than this) and offering them dirt also. The important thing to me isn't if Russia (who I already expect to be obtaining dirt on Pols both legally and illegally, just like we I expect are) has dirt, or how it was obtained, it's that there is dirt to collect on a POTUS candidate to begin with. I know it's crazy, but, I expect Politicians to be clean, or at least that's my desire. So if the Russians, or anyone else really, actually turns up damaging dirt on any political candidate, I really care not where it came from, I care that it is what it is in the first place.
If they have credible audio and/or video, or credible e-mail trail of someone in the Trump campaign, or, someone acting to support the Trump campaign who was actually supposed to be doing so (not a false flag Dem operation), asking the Russians (or anyone else) to do something illegal, or, engaging in quid pro quo where they get dirt and give them consideration that the US would not otherwise bestow down the road, I have no problems with that person being legally - and socially - sanctioned. Why would I?
Now, when WikiLeaks, who has a 100% accuracy record, had item after item about Team Billary, and the entire mainstream media save for Fox was doing their absolute best to parrot the It's Russia! Team Billary supplied cover, you guys were in here screaming that that was BS and the media and public had a right to know, right? I'll just say up front, I don't remember that. I remember mitigation after excuse after dodge. But now, now after Team Blue lost 2016 (after expecting to win big), we need to go full tilt OMG Russia! and get it all investigated? Spare me the fake concern man...
