When the U.S. dropped atomic bombs on Hiroshima and Nagasaki in August 1945, “Carousel” was doing boffo business on Broadway.

She headlined a boffo political convention in August and easily bested Donald Trump earlier this month in their one, and possibly only, debate.

So her boffo performance — it is, after all, a performance — was not surprising.

That said, Biden could be boffo — or at least perform decently enough.

Come summer, I saw the trend expand with the boffo success of “Barbie,” in which Ryan Gosling’s Ken makes an entire career out of pouting on the beach.
