From a Wall Street Journal editorial headlined “Breaking the Biden Age Taboo”:

A pastime around our office in early 2021 was guessing when Democrats would begin to point out that President Biden was too old for the job and should pack it in. The consensus was after a drubbing in the midterm election, but congrats to the colleague (he knows who he is) who figured sometime early this year. He wins the office pool because the drive to shove the President out the door has already begun.
