Real change never occurs from the top on down, [but] always from the bottom on up.

The focus, to my mind, is to make sure that Donald Trump does not become president of the United States. I think by temperament he is unqualified to be president. I think his views - you have a guy who's running for president who rejects science, doesn't even believe climate change is real, let alone wants to do something about it, wants to give hundreds of billions of dollars in tax breaks to the top two-tenths of one percent.

What my campaign is about is a political revolution - millions of people standing up and saying, enough is enough. Our government belongs to all of us, and not just the hand full of billionaires.

I am very, very, very concerned about the United States getting drawn into an endless war, year after year after year.

We are spending hundreds of billions of dollars maintaining 5,000 nuclear weapons. I think we need major reform in the military, making it more cost effective, but also focusing on the real crisis that faces America.

I congratulate Secretary [Hillary] Clinton on her victory. But, I think, for us, that is about as bad as it's going to get.

I know a great country that needs to be rebuilt in terms of roads, bridges, schools. That is called the United States of America.
