The 30-second spot, titled "Strive," opens with a clip of President John F. Kennedy’s famous speech in which he called for the U.S. to send a man to the moon, saying, “We choose to go to the moon in this decade and do the other things, not because they are easy, but because they are hard.”

“President Kennedy knew settling for half-measures wasn't good enough,” Sanders says in voice-over over images from his own campaign as well as images from the Franklin Roosevelt and Lyndon Johnson administrations, the civil rights and women’s liberation movements, and protests for climate action.

“So when candidates say we can’t guarantee health care for all, make college affordable for all, combat climate change, or create a world at peace, remember that America is best when we strive to do big things, even when it’s hard,” Sanders adds.
