In an interview, Sunday with ABC's "This Week" host Jonathan Karl, Sen. Bernie Sanders said he hopes the 2020 Democratic presidential primary will be about issues and not personal attacks.
JONATHAN KARL: I'm sure you saw Joe Biden say that he is the most progressive candidate in this race.
SEN. BERNIE SANDERS: Yes. Look, Joe is a good friend of mine, and I’m not here to attack Joe. Joe voted for the war in Iraq. I led the effort against it. Joe voted for NAFTA and permanent normal trade relations -- trade agreements with China. I led the effort against that. Joe voted for the deregulation of Wall Street. I voted against that. You know, I think if you look at Joe's record, and you look at my record, I don't think there's much question about who's more progressive.
KARL: You famously said of Hillary Clinton during the last campaign, "I disagree with Hillary Clinton on virtually everything". Would you say the same thing about Joe Biden?
SANDERS: Well, we’ve got to see -- this is early in the campaign.
KARL: But -- but you've known Biden a long time.
SANDERS: Well, I disagree with many of the votes that he cast, he and I voted in very different ways. I have stood up for the right of people to have healthcare because they're an American citizen. I don't think that's Joe's position. What I do want to say, Jonathan, is that I hope on the Democratic side, that what the campaign is about is a discussion of issues, not personal attacks. I think I can feel safe to say that no matter who the candidate is, we are all going to come together to defeat the most dangerous president in modern American history, and that is Donald Trump.
