impairment

Trump hasn’t had a stroke or suffered a neurological disaster, and his behavior in the White House is no different from the behavior he manifested consistently while winning enough votes to take the presidency.

But he is nonetheless clearly impaired, gravely deficient somewhere at the intersection of reason and judgment and conscience and self-control. Pointing this out is wearying and repetitive, but still it must be pointed out.

You can be as loyal as Jeff Sessions and still suffer the consequences of that plain and inescapable truth: This president should not be the president, and the sooner he is not, the better.

Ross Douthat. The point could hardly be put more neatly, more accurately, and more depressingly.
