What the American people want to see in their president is somebody who not necessarily can win every fight, but they want to see him stand up and fight for what he believes, take his case to the American people.

In the last presidential election Obama and Romney raised about $1 billion each. The Koch brothers, the second wealthiest family in America, now say they will raise nearly $1 billion for the 2016 elections. When one family can raise as much as an entire party, the system is broken. This is oligarchy, not democracy. We must overturn Citizens United.

There's no question to my mind and I think no question to any objective observer's mind that the DNC was supporting Hillary Clinton and was at opposition to our campaign. So I'm not quite shocked by this. And that is why many, many months ago I made it clear that I thought Debbie Wasserman Schultz should resign, should step down.

We must fundamentally restructure our student loan program. It makes no sense that students and their parents are forced to pay interest rates for higher education loans that are much higher than they pay for car loans or housing mortgages.

We are rapidly moving toward a nation of the super-rich, by the super-rich and for the super-rich

The light bulb going off in my head was a fear that in this pivotal moment in history, when America faces so many serious problems, when the middle class and working class of this country are being decimated, that there were not voices out there representing the tens of millions of people who needed a voice. And the idea of going through a campaign where there is not a serious discussion about the most important issues facing America, where there are not voices out there representing people who are hurting - that seemed to me unacceptable.

Goldman Sachs was one of those companies whose illegal activity helped destroy our economy and ruin the lives of millions of Americans. But this is what a rigged economy and a corrupt campaign finance system and a broken criminal justice is about. These guys are so powerful that not one of the executives on Wall Street has been charged with anything after paying, in this case of Goldman Sachs, a $5 billion fine.
