SPIEGEL: You make it sound as though lots of people were responsible for Clinton's defeat -- the director of the FBI, the Russians -- and just not you. Hillary Clinton said similar things a few days ago in an interview with CNN. What mistakes did you make?
Podesta: No question: We made mistakes. We probably under-resourced Wisconsin. We were confident we would win there. We had a fairly full field team there, way more people than Obama did. But we didn't advertise there. We thought it wasn't necessary. Trump had no presence in the state, so we thought we didn't need any. But the National Rifle Association advertised heavily there. We underestimated that.
SPIEGEL: That can't be the only mistake.
Podesta: We were unable to get out of the loop that Trump created and that the media created of outrageous statement reaction, new outrageous statement counterreaction. That left an opening for a lot of people to think that this conversation really wasn't about them. And the media was thankful for a reality TV candidate. Most of the media turned into accomplices of Donald Trump.
SPIEGEL: There was another surprisingly successful Democratic Party contender: 75-year-old Bernie Sanders. Did he have a chance of winning the election?
Podesta: We took him seriously very early. There's the theory that he could have gotten some of these angry white working-class voters that went to Trump that Clinton couldn't get, and particularly the Obama Trump voters. That's true. He probably could have gotten a few of them. But not enough. We talked to him, early on. We wanted him to be part of our campaign. After the New York primary, which was in mid-April, after Super Tuesday, which was in early March, it was clear that he couldn't catch us. But he wanted to keep going. It was his decision.
