Our Principles PAC, a group run by Republican operatives seeking to stop Donald J. Trump’s presidential campaign, released a new 60-second commercial highlighting some of Mr. Trump’s most sexist statements.

On Screen

“Bimbo.” “Dog.” “Fat pig.” “A person who is very flat-chested is very hard to be a 10.” The ad is called “Quotes,” and it mainly consists of seven women, young and old, taking turns pointedly delivering lines originated by Mr. Trump — some of them necessarily bleeped. The quotations include references by Mr. Trump to Rosie O’Donnell (“that fat ugly face of hers”), Princess Diana (“she was crazy, but these are minor details”), the Fox News host Megyn Kelly (“blood coming out of her wherever”) and other women.

The women delivering Mr. Trump’s lines stand against a simple white backdrop. There are no pictures or video clips of him, no music. His insults and sexual innuendoes are read aloud with biting disapproval.

“This,” says one middle-aged actress, after 45 seconds of the quotations, “is how Donald Trump talks about our mothers.” Another middle-aged woman adds: “Our sisters.” A much younger woman adds: “Our daughters.” Finally, a female narrator asks viewers who believe America deserves better to “vote against Donald Trump.”
