It was a moment that embodied the tension for New Yorkers in African-American communities toward the police and made “I can’t breathe” a nationwide rallying cry. Now, the daughter of Eric Garner, the Staten Island man who died during an arrest after he was placed in a chokehold by police officers, lends her support to Senator Bernie Sanders in a 30-second recut version of an ad first released in January.

On Screen

Mr. Garner’s daughter, Erica Garner, and her own young daughter embrace and smile as Ms. Garner says, “This is everything that I have, my family.” The infamous footage of her father being arrested, placed in a chokehold and taken to the ground fills the screen, as she recalled, “I got to see my dad die on national TV.” An old family photo of Mr. Garner quickly shifts to protests, of “die-ins” and of marchers chanting Mr. Garner’s last words, “I can’t breathe.” Mr. Sanders then makes his appearance in the ad, shown at the podium of one of his rallies, as Ms. Garner says: “People are dying. We need a president that will talk about it.”

Archival footage appears of a young man in dirt-splattered jeans being cuffed and arrested, his head shoved down; the onscreen text identifies the footage as “Bernie Sanders Civil Rights Protest 1963.” Ms. Garner says, “I believe Bernie Sanders is a protester.” More archival footage of the police cracking down on that protest slowly builds to a climax, along with the symphonic music, as a policeman slams closed a van door and the ad cuts to black. Ms. Garner is then shown sitting on a couch. “That’s why I’m for Bernie.”

The Message

That Mr. Sanders is “one of us,” a protester and one who has stood by the civil rights movement for decades, and is not just pandering. Much like how Mrs. Clinton has a similar powerful ad featuring Morgan Freeman proclaiming that she “stands with us,” Mr. Sanders has Ms. Garner making the case for him.
