It reads more like a manifesto than anything else. There is the slight possibility that someone is having the NYT on, taking a piss to set them up, but if that is not the case the idea that we have reached a point in US history that such resistance is deemed necessary by people in a President's party is nothing short of astounding.
"Unprecedented" has been used, perhaps overused at times, but we have factually entered an era where that is precisely where things stand. In terms of action, this is not unimaginably removed from an actual coup, one that many would approve of because the Constitution has been attacked by enemies domestic in office.
I've been surprised and heartened at how many liberals have come out and said this it not okay.
If you think a president is so badly compromised due to stupidity, ignorance, corruption, whatever, you need to say so publicly and attempt to get him removed from office. You don't quietly sabotage him. Establishing a norm where the executive branch tries to thwart the president's will because they are unwilling to use the mechanisms provided by the Constitution is not okay. We have an answer and the means through which to remove him. Either try that way or resign publicly and let the world know you are resigning because the president is insane.
