Can we talk, for a minute, about the men?

Not so much President Obama, who in his appearance at the Democratic National Convention on Wednesday was as polished and powerful as ever, extolling the American myth and passing the torch of leadership to Hillary Clinton. Mr. Obama recast himself in the role of elder statesman, complete with silver tie, to match the hair that has silvered in office.

Not so much Michael R. Bloomberg, the former mayor of New York, now an Independent as demonstrated by his neither red nor blue but purple tie, who pointedly declared his allegiance to Mrs. Clinton and called her opponent, Donald J. Trump, a “dangerous demagogue.”

Not even former President Bill Clinton, who has a complicated road ahead of him building an image of a first man (first spouse?) and who chose, on Tuesday night, the current default Washington option that once upon a time was Mr. Obama’s trademark look: dark suit, white shirt, blue tie.

But Tim Kaine. Over the last few nights of the Democratic convention, which was chockablock with national figures, his image was not like the others. It stood out for a reason.
