No, and that's the point and what will get him through.
I'm in 2 minds on this. I'm not averse to some levels of conspiracy theory, and this really lends itself.
Viceregal , the so called "proof" if it exists, is in the hands of the Russians. They're not about to release anything, as the point is to have Trump in the Whitehouse with this stuff hanging over his head. It will be kept well and truly up his sleeve. The only hope is that some now know where to dig, but that will be a big task & take a while. It seems that there is good intelligence on what cards the Russians hold, but we can't actually see those cards.
On the other hand, I don't for one second put it past U.S. intelligence agencies to manufacture things. There are political players more influential than Trump who by now will be panicking at the prospect of this madman being President. To be honest, I don't mind some subterfuge in this instance if it is a means to the end of Trump.
Bottom line is, I don't care if any of it is true or not as long as the end result is the downfall of this lunatic.
To pick up on TBD's point, I actually find it most disturbing that most of the world seems concerned about paying prostitutes to piss on each other. I mean **** me, that is the least of our worries. If true, the goose is in cahoots with the Russian lunatics and has just perverted the course of democracy (which of course he was already guilty of without their help). This is huge.
