A year has passed since highly credentialed intelligence professionals produced the first hard evidence that allegations of mail theft and other crimes attributed to Russia rested on purposeful falsification and subterfuge. The initial reaction to these revelations—a firestorm of frantic denial—augured ill, and the time since has fulfilled one's worst expectations.

One year later we live within an institutionalized proscription of proven reality. Our discourse consists of a series of fence posts and taboos. By any detached measure, this lands us in deep, serious trouble. The sprawl of what we call "Russia-gate" now brings our republic and its institutions to a moment of great peril—the gravest since the McCarthy years and possibly since the Civil War. No, I do not consider this hyperbole.
