CNN: Democratic presidential candidate Sen. Bernie Sanders defends his voting record against former Vice President Joe Biden's, telling CNN's Anderson Cooper he hopes all of the candidates run campaigns that focus on issues and not personal attacks.
ANDERSON COOPER: You talk about unions. Former Vice President Biden was in front of firefighters union, obviously organized labor is a critical support in a Democratic primary.
Are you concerned that Biden can make inroads there, that Biden has a leg up there?
SEN. BERNIE SANDERS: Well, look, I'm running against, I think, 19 other people. So I'm concerned about everybody.
But I think when people take a look at my record versus Vice President Biden's record, I helped lead the fight against NAFTA. He voted for NAFTA. I helped lead the fight against PNTR with China. He voted for it.
I strongly opposed the Trans-Pacific Partnership. He supported it. I voted against the war in Iraq. He voted for it.
So I think what I hope, Anderson, what this campaign is about -- and I have to tell you, I like Joe Biden. Joe is a friend of mine. But I think what we need to do with all of the candidates, have an issue- oriented campaign, not personal attacks, but talk about what we have done in our political lives, what we want to do as president, and how we're going to transform our economy so that it works for all of us and not just the 1 percent.
