The American people understand that we need real change in this country, in my view, a political revolution, which says to the people on top, "You know what, you guys can't have it all."

I want to know in this day and age, whether it is possible for any candidate who is not a billionaire or who is not beholden to the billionaire class, to be able to run successful campaigns.

At a time when our planet is warming due to climate change, the last thing our environment needs is more drilling. What we need is for Congress and the White House to move toward clean energy such as solar, wind and geothermal.

The Republicans are many things, but they're not dumb. And if millions of people begin to stand up and fight back, they're going to be thinking twice about doing very bad things.

I am very proud to be the only candidate up here who does not have a Super PAC, who's not raising huge sums of money from Wall Street...

We`ve got to stand with those people who are being attacked today, but at the same time, it`s not good enough to say that racism and xenophobia is bad. We`ve got to reach those people today who are so angry, who are so hateful and say, yes, you have a right to be angry, don`t take it out on the Muslims. Work with us to create an agenda and political movement that will make your life better, not just other people`s life worse.

I'm very proud that the state of Vermont banned fracking. I hope communities all over California, and all over America do the same.
