I have worked in Congress.
And the level of heat a playful sarcastic quip has elicited here is a fine example of just how far beyond the pale this discussion has become.
Nancy Pelosi hasn't avoided impeachment because she loves Trump, or because she's stupid, or because she's a coward. She has resisted it because she honestly believed it would do more political damage to Democrats than to Republicans. And since there was no chance the Senate would vote to remove Trump, that makes it, in her determination, a bad move, both politically and for the prospects of liberal policies in the future.
You can disagree with her on that front, and you should absolutely voice those disagreements. But the abject vilification of a woman who has spent her life fighting for progressive causes and the American people is, frankly, both unhelpful and incredibly disturbing. And I don't mind saying so.
