"Schiff was not exaggerating when he called Dershowitz argument a descent into constitutional madness.” It may even prove more pernicious than the simple fact of Trump’s acquittal—which was preordained, given the Republican majority’s fealty to him—because the standard it sets for Presidential accountability is so degraded. It’s easy to imagine defense teams playing a video of Dershowitz’s presentation at a future impeachment trial, in an effort to exonerate another rogue President. Perhaps the Republican senators, as they trudged toward casting their vote, were making a calculation about how Trump might return the favor with one for them, or their party, or their country. Or maybe they, too, can no longer tell the difference."
