ROGER KIMBALL: The real impeachment scandal: The Democrats are always guilty of what they accuse Trump of. “If anything has become clear over the past couple of months, it is that the Democrats have no case against the president; there are no crimes alleged, just the emission of a turgid vapor about ‘abuse of power’ and ‘obstruction of Congress’. There was no ‘quid pro quo’, no ‘pressure’, no ‘abuse of power’. All people with first hand knowledge of the infamous conversation between President Trump and President Zelensky acknowledge this. There was just the president doing the people’s business, legitimately exercising his power. . . . In this case, the real Ukraine scandal is the Biden family scandal. Yet somehow Joe and Hunter Biden’s corruption got transmuted in supposed wrongdoing by Donald Trump. How does that work? ‘How Did the Bidens’ Corruption Become Trump’s Scandal?‘ It’s the special alchemy at which Democrats excel. Republicans never learned the knack.”
