“All the way up until the end, a lot of people highly identified with his campaign were urging people to vote third-party, urging people not to vote,” Clinton, 72, told Emily Tisch Sussman on her podcast Your Primary Playlist. “It had an impact.”

Clinton lauded former President Barack Obama’s behavior during the 2008 election, when he defeated her for the party’s nomination, claiming he helped unify the Democratic Party in a way Sanders did not eight years later.

“That cannot happen again,” she said, alluding to the 2020 election. “I don’t care who the nominee is. I don’t care. As long as it’s somebody who can win, and as long as it’s somebody who understands politics is the art of addition, not subtraction.”
