I did a lot of reading. I read about democratic socialism. And I read about the efforts of people for such a long time trying to create a society in which all people can live with dignity. And that's kind of what I believe.

I think we are making progress, but we have long way to go. People also have got to understand the agenda that we are fighting for. This is a senator who has taken on every powerful special interest, whether it's Wall Street, whether it's drug companies who are ripping off the American people, the military industrial complex.

All I can say is if you check my record going back a long time, I have stood with those who are hurting. I have stood with those who have no money.

I think we bring together that broad coalition including Russia to help us destroy ISIS and work on a timetable to get rid of Assad, hopefully through Democratic elections. First priority, destroy ISIS.

To be honest with you, I worry about concentration of ownership in media, where you have a handful of media conglomerates largely controlling what we see, hear and read.

The truth is we have a political system and an economic system controlled by a few extremely wealthy people. Not Barack Obama, not Bernie Sanders, no one person has the influence by himself or herself to take on this enormous array of power unless millions of people begin to work together to demand changes.

I am proud of the campaign that we ran. Obviously, I wish we could have done a little bit better.
