I'm thrilled the president [Barack Obama] has endorsed me. We started off as fierce competitors, and we've ended up as true friends and partners and worked together on so many important issues.

It's really hard to get to know me, or any candidate. And I would be asked questions like, well, why are you really running for president?

I have a comprehensive energy policy, but it really does include fighting climate change, because I think that is a serious problem.

I was a baseball fan, at any rate.

I like live audiences, with real people - virtual reality is no substitute.

We can do better. ...We can't ignore the inequalities that persist in our justice system that undermine our most deeply held values of fairness and equality.

I am a sensitive person, so it is actually saddening to learn that these poverty-stricken families are most of the time mistreated or looked down upon. Help the poor, like how you would want to be helped if you were in their position.
