This argument strikes me as willfully obtuse (in the 20thC impeachment has been about a preponderance of wrongdoing, not a single gotcha), but I offer it to contrast most of what I’ve shared over the past few days:
OPINION: The Comey memo offers zero evidence to impeach Trump

For the record, over the past week it’s become increasingly clear that our representatives need to start saying the word “impeachment“—which is, recall, a formal Congressional statement of charges and investigation, not a fancy way of saying “removal from office.” Is it time for removal from office? I have no fucking clue. Is it time to formally level charges? It sure seems that way—but I don’t know, and am in no position to figure it out. It is certainly time for us to accept that we need to seriously talk about this, not just throw the word around in histrionic fits. It’s like the word “cancer” or the phrase “I’m dying”: We use these a lot as shorthands for things like “I feely sorta achy” or “I’m super-duper tired,” but there are also times when you do have cancer, when you are dying, and you need to actually start to talk about that with your loved ones.
And we’re in that place now, the place where we have to talk about cutting off our nose not to spite our face, but to save it before the cancer metastasizes.
This isn’t because the PotUS fired Comey for the stated reason that he was sick of “this Russia thing,” and it isn’t because he spilled the beans to that same hostile foreign power, and it isn’t because he tried to obstruct the early stages of the investigation into Trump-Russia ties back in February and it isn’t because he quite clearly benefited from—and plausible in some form, by action, inaction, or willful ignorance, colluded with—election meddling by that foreign power. It isn’t because he, his staff, and his family have very publicly sought to personally profit from holding the Office of the PotUS, and it isn’t because everyone in his inner circle seems to treat the very notion of “ethics” the way a dog treats an especially sexy throw-pillow, and it isn’t because of the breaking-strain bend he’s put in the Emoluments Clause, and it isn’t because of his stated seditious animosity to the rule of law as it is widely recognized in this country—especially as pertains to the 1st, 4th, and 14th Amendments. It is because of the preponderance of those things and more, taken all together, without pause, without recrimination, without apparent shame or the recognition that each of them is not simply Bad, but actually contemptuous of the very notion that governments are instituted among regular folks like us (not inflicted upon them) and derive their powers from the consent of the governed (which again, is us). His high crime, if nothing else, is that he acts with contempt for us and for our institutions.
“What is his impeachable offense?”
Dude, at this point, what isn’t?
