When the Democrats were choosing their Presidential candidate, I wrote that what America needed  just now was “a do-nothing President” and that Sleepy Joe Biden was the man for the job. Calling him “Sleepy Joe” was a bit unkind and “do-nothing” not quite right.  Nevertheless, what I was implying seems to me to hold good; indeed, it does so more than ever. The mood in the United States is febrile. The nation needs to calm down.
