The Clinton campaign is continuing to focus its negative advertising efforts on provocative remarks made by Donald J. Trump, this time in a commercial that invites adults to imagine what a child might be learning from his campaign.

Soft, inviting piano tones are set against a pink sunset and a neighborhood at dusk, before Mr. Trump’s voice interrupts the tranquil scene. “I love the old days. You know what they used to do to guys like that when they were in a place like this? They’d be carried out on a stretcher, folks,” Mr. Trump is heard telling a crowd. More of his acidic comments are played, while the screen is filled with close-ups of children gazing at television sets, seemingly soaking up every R-rated remark.

“Our children are watching,” a text card warns after two small children watch a scene of Mr. Trump appearing to mock a reporter with a disability. At the end, Hillary Clinton is shown delivering a speech on children, closing with, “We need to make sure that they can be proud of us.”

THE MESSAGE The ad paints Mr. Trump as unpresidential and unfit for office, in the eyes of both children and, the ad assumes, their voting parents (who, one could argue, might not be too happy with the Clinton campaign’s rebroadcasting of the messages to children watching television). The Clinton campaign has also made Mrs. Clinton’s record of working for children and families a central focus, while trying to portray Mr. Trump as a poor role model to children.
