Seldom mentioned among the motives behind the persistent drumming on alleged Russian interference was an over-arching need to help the Security State hide their tracks.
The need for a scapegoat to blame for Hillary Clinton's snatching defeat out of the jaws victory also played a role; as did the need for the Military-Industrial-Congressional-Intelligence-Media-Academia-Think-Tank complex (MICIMATT) to keep front and center in the minds of Americans the alleged multifaceted threat coming from an "aggressive" Russia. (Recall that John McCain called the, now disproven, "Russian hacking" of the DNC emails an "act of war.")
But that was then. This is now.
Though the corporate media is trying to bury it, the Russiagate narrative has in the past few weeks finally collapsed with the revelation that CrowdStrike had no evidence Russia took anything from the DNC servers and that the FBI set a perjury trap for Gen. Michael Flynn.
