You can't become a billionaire stepping over children sleeping on the street.

I think it is now widely understood that the so-called "War on Drugs" has largely been a failure. Too many people have developed criminal records for smoking marijuana. Too many people have gone to jail for nonviolent crimes. So I think it's important for us to rethink the war on drugs.

It is time to tax and regulate marijuana like alcohol. It is time to end the arrests of so many people and the destruction of so many lives for possessing marijuana.

I believe what I call common sense gun reform. Plus, a revolution in mental health, making sure that if people are having a nervous breakdown, or are suicidal, or homicidal, they get the care they need when they need it. I think the vast majority of the American people can support and agenda composed of those features.

People are hungry, and they're hurting and they're very, very worried about their children. Will their kids ever pay off their student debt? Will their kids ever get a decent-paying job? I think Democrats have got to be running a grass-roots campaign - mobilizing people and being prepared to take on the 1 percent with an agenda that speaks to the needs of ordinary workers.

Every major country on earth, whether it's the U.K., whether it's France, whether it's Canada, has managed to provide healthcare to all people as a right and they are spending significantly less per capita on health care than we are. So I do not accept the belief that the United States of America can't do that.

20 million people thrown off of health insurance, prescription drug prices raising for seniors, privatization of Medicare: devastation. And we've got to fight back against that.
