I can understand distaste for Obama (though I don't share it), and distrust of the Clintons (which I do share).  But if Jenkins can't see that these people don't belong in the same truthiverse as Trump, I can't help him.  To me, that's as obvious as the difference between night and day.

Obama and the Clintons lied in the traditional political manner--relatively limited lies to conceal shortcomings or deflect blame.  They understood the difference between truth and lie, and assumed that being caught in the latter was politically damaging.  Trump, on the other hand, lies in the expansive sense of simply not caring about the difference.  Trump's pathological psychology seems to tell him that whatever looks in his interest to say now must be true, and by a sort of galloping process, the "truth" tomorrow can simply cancel out yesterday's "truth."  Trump's lies aren't just quantitatively far beyond those of the Democrats, they are qualitatively as different as one species from another.
