Now that the Senate impeachment trial of one Donald J. Trump is actually upon us, I’m preparing myself for long days with C-SPAN, for the onslaught of truth-challenged Trumpian tweets, for the name-calling that will likely reach record decibel levels, for Jason Crow’s big debut on the national stage, for the unlikely, made-for-SNL return of Clinton-hounding Ken Starr as Trump defender, and, yes, for the inevitable letdown once it’s over.

It is way too late to be shocked when Donald Trump — now apparently running for re-election as a full-throated racist — attacks a majority-black city like Baltimore as a “disgusting rat and rodent infested mess” in one tweet, which he followed with, “No human being would want to live there.”

We can all agree that Nancy Pelosi is driving Donald Trump crazy, by which I mean, of course, crazier than usual. We can agree, too, and that no one has ever gotten this far into his head — not Comey, not Mueller, not anyone.

So now that we have the damning Mueller Report, or much of it, in hand, the obvious question is what the hell we should do with it.

As we all know, Donald Trump is the sociopathic liar of our time and, just possibly, of any time. It’s not only that he lies so frequently, but that he lies so brazenly. But knowing that he lies doesn’t solve one the great puzzles of the Trump era — whether the guy himself actually believes anything that comes out of his mouth.
