I'm happy to talk to anybody about anything.

After I win the job and even in the course of seeking it, we're going to be building bridges. And we're going to be meeting people and addressing the concerns that they have.

I'm an optimistic guy.It's just as much the case that people will come to me and ask my opinion about how to properly include the Muslim community, as it is that people will come with some hateful stuff too. When people come to me about my religion, it's not always a thing of "we don't want people like you here," which happens sometimes. But mostly it's people who would like to know more. I get a chance to help people understand the religion better.

Worked hard on [our message of strengthening the middle class, working people], but it didn't come through in places like Wisconsin, Michigan, Pennsylvania.It really should have, because people are struggling. And the Democratic message and the Democratic platform would help them, but somehow it didn't come up the way it should have. But it will.

I'd say the most important criteria is vision. What is your vision for the party? Do you have a vision to strengthen the grassroots and help them turn out people in their local communities? That's the real thing. The real question is not about one person. It's not about an individual. It's about millions of people working all over this country to reach out in their local communities. And the DNC chair has to help them do that and have a vision for that and have the energy for that.

Now [in 2016] I have the highest turnout in the state of Minnesota. And Minnesota is the highest turnout state in the country.

I'm not here to say what [Clintons] did wrong. I mean, there's going to be plenty of post-mortem review of what should have gone differently.
