Thing of it is, though, the Russians have never made more than cursory denials of their involvement. Gene Lyons pointed out that if they thought they were going to get away with it they would have covered their tracks a lot better. As it is, it's thunderously obvious that the Russians worked on many different levels to tilt the election towards Trump. It's equally obvious that the motive for doing so was to diminish confidence in the office of the Presidency and that the best way forward now that their guy is in office is to give half the country reason to doubt he's legitimate, same as they would have done had Clinton won. I'm not even sure what losing outcome is possible here for Russia. Trump could call a press conference, confess to everything and cooperate 100% in transitioning power to a new administration (there's a sticky wicket) and we'd still have Nazis marching in Charlottesville and a #MAGA mass insisting the liberal conspiracy was sapping their precious bodily fluids.
